Genesis 37–39 begins the extended account of Joseph and, in the middle of that narrative, records an important episode in the family of Judah. These chapters show the destructive power of envy, hatred, deception, and sexual sin, while also displaying the faithfulness of a man who feared God under severe temptation and the sustaining presence of the LORD in affliction.

A controlling statement for Genesis 39 is repeated plainly in the text: “the LORD was with Joseph” (Genesis 39:2, 21). Joseph’s circumstances changed dramatically—from his father’s household, to slavery, and then to prison—but the LORD’s presence did not change.

Genesis 37–39 does not yet explicitly explain God’s full purpose behind everything that happened to Joseph. Later Scripture does. Looking back upon these same events, Joseph said to his brethren:

“But as for you, ye thought evil against me; but God meant it unto good, to bring to pass, as it is this day, to save much people alive.”
— Genesis 50:20

Thus, God’s providential purpose is certain from the later KJV text, though Genesis 37 itself does not state that purpose while the events are unfolding.

Chapter Summaries

Genesis 37 — Joseph Hated, Sold, and Taken into Egypt

Joseph is introduced at seventeen years old:

“Joseph, being seventeen years old, was feeding the flock with his brethren.”
— Genesis 37:2

He brought unto his father “their evil report.” The text does not tell us the specific content of that report, so it would be improper to speculate about what his brethren had done.

Israel openly loved Joseph more than his other children:

“Now Israel loved Joseph more than all his children, because he was the son of his old age: and he made him a coat of many colours.”
— Genesis 37:3

The unequal affection is explicit. The passage does not expressly pronounce judgment upon Jacob for it, although the resulting family hostility is equally explicit:

“And when his brethren saw that their father loved him more than all his brethren, they hated him, and could not speak peaceably unto him.”
— Genesis 37:4

Joseph’s dreams

Joseph dreamed two notable dreams.

In the first, the sheaves of his brethren bowed to his sheaf. In the second:

“behold, the sun and the moon and the eleven stars made obeisance to me.”
— Genesis 37:9

His brethren understood the dreams as implying Joseph’s future exaltation over them. His father rebuked him concerning the second dream, while also observing the saying.

Genesis 37:11 makes an important distinction:

“And his brethren envied him; but his father observed the saying.”

The chapter says that Joseph dreamed these dreams, but Genesis 37 does not explicitly say in so many words that God sent them. Their significance becomes clearer as the Genesis account continues; we should therefore avoid claiming more at this point than the text states.

Joseph sent to his brethren

Israel sent Joseph from the vale of Hebron to check upon his brethren, who had gone toward Shechem. Joseph eventually learned that they had moved on to Dothan.

When his brethren saw him coming:

“even before he came near unto them, they conspired against him to slay him.”
— Genesis 37:18

They mockingly called him:

“this dreamer”
— Genesis 37:19

Their intended plan was murder followed by deception:

“Come now therefore, and let us slay him, and cast him into some pit, and we will say, Some evil beast hath devoured him.”
— Genesis 37:20

Reuben’s intervention

Reuben sought to prevent Joseph’s death:

“And Reuben heard it, and he delivered him out of their hands; and said, Let us not kill him.”
— Genesis 37:21

Verse 22 explicitly gives Reuben’s intention: he planned “to rid him out of their hands, to deliver him to his father again.”

The brothers stripped Joseph of his coat and cast him into a pit. Scripture specifically notes:

“and the pit was empty, there was no water in it.”
— Genesis 37:24

Then, with Joseph in the pit:

“they sat down to eat bread.”
— Genesis 37:25

That detail presents a sobering picture of their hardness toward their brother.

Joseph sold

Judah argued against killing Joseph:

“What profit is it if we slay our brother, and conceal his blood?”
— Genesis 37:26

He proposed selling him instead:

“for he is our brother and our flesh.”
— Genesis 37:27

Joseph was sold for:

“twenty pieces of silver”
— Genesis 37:28

Care is needed with the groups named in this passage. Genesis 37:28 mentions “Midianites merchantmen” and says Joseph was sold “to the Ishmeelites.” Genesis 37:36 then says:

“And the Midianites sold him into Egypt unto Potiphar.”

The chapter uses both designations but does not stop to explain their relationship. It is therefore safest simply to retain the wording Scripture gives rather than construct details the text does not supply.

Jacob deceived

Joseph’s coat was dipped in the blood of a kid of the goats and sent to Jacob. Jacob reached the conclusion:

“It is my son’s coat; an evil beast hath devoured him; Joseph is without doubt rent in pieces.”
— Genesis 37:33

That conclusion was Jacob’s belief; Joseph had not actually been killed.

Jacob mourned deeply:

“I will go down into the grave unto my son mourning.”
— Genesis 37:35

Meanwhile, Joseph was alive in Egypt:

“And the Midianites sold him into Egypt unto Potiphar, an officer of Pharaoh’s, and captain of the guard.”
— Genesis 37:36

The chapter therefore closes with a striking contrast: Jacob believes Joseph dead, while Joseph has been carried into an entirely different stage of his life.

Genesis 38 — Judah and Tamar

Genesis 38 temporarily turns from Joseph to Judah.

Judah departed from his brethren and associated with Hirah an Adullamite. Judah saw the daughter of a Canaanite named Shuah, married her, and had three sons:

• Er
• Onan
• Shelah

Shelah was born at Chezib.

Er and Onan

Judah took Tamar as a wife for Er.

Scripture gives a direct divine judgment concerning Er:

“And Er, Judah’s firstborn, was wicked in the sight of the LORD; and the LORD slew him.”
— Genesis 38:7

The particular wickedness of Er is not identified. Anything more specific would be speculation.

Judah then commanded Onan to fulfill his responsibility toward his deceased brother’s wife:

“Go in unto thy brother’s wife, and marry her, and raise up seed to thy brother.”
— Genesis 38:8

Onan deliberately prevented conception because:

“he knew that the seed should not be his.”
— Genesis 38:9

The text then states:

“And the thing which he did displeased the LORD: wherefore he slew him also.”
— Genesis 38:10

The passage therefore presents Onan’s deliberate conduct and motive together. We should not reduce the sin merely to one physical act while ignoring his refusal concerning his brother’s seed.

Tamar and Shelah

Judah instructed Tamar to remain a widow until Shelah was grown. Scripture explicitly gives Judah’s reasoning:

“for he said, Lest peradventure he die also, as his brethren did.”
— Genesis 38:11

Later, Shelah had grown, but Tamar had “not been given unto him to wife” (Genesis 38:14).

After Judah’s wife died and he had been comforted, he went toward Timnath for the shearing of his sheep.

Tamar disguised herself and sat by the way to Timnath. Judah did not recognize her. Their resulting conduct is described plainly by Scripture, but there is no need to embellish the account beyond what God has written.

Tamar received Judah’s signet, bracelets, and staff as a pledge.

She conceived.

Judah confronted by his own tokens

About three months later, Judah was told that Tamar was with child. When Judah pronounced judgment upon her, Tamar produced his identifying possessions.

She said:

“By the man, whose these are, am I with child.”
— Genesis 38:25

Judah recognized them and confessed:

“She hath been more righteous than I; because that I gave her not to Shelah my son.”
— Genesis 38:26

This wording should be kept precise. Judah did not say that everything Tamar had done was righteous. He specifically connected his statement to his own failure to give her Shelah.

The verse immediately adds:

“And he knew her again no more.”

Pharez and Zarah

Tamar bore twins, Pharez and Zarah. Though Zarah’s hand appeared first and a scarlet thread was placed upon it, Pharez was actually born first.

The chapter closes:

“Therefore his name was called Pharez.”
— Genesis 38:29

Genesis 38 itself does not state the later significance of Pharez, but later KJV Scripture explicitly places him in the line leading to Jesus Christ:

“And Judas begat Phares and Zara of Thamar”
— Matthew 1:3

Thus, the connection of Pharez to the earthly genealogy of Christ is not speculation; it is expressly stated later in Scripture.

Genesis 39 — Joseph in Potiphar’s House and in Prison

Genesis 39 returns to Joseph in Egypt.

“And Joseph was brought down to Egypt.”
— Genesis 39:1

Potiphar, an Egyptian officer of Pharaoh and captain of the guard, purchased him.

Then comes the great controlling truth of the chapter:

“And the LORD was with Joseph, and he was a prosperous man.”
— Genesis 39:2

Notice carefully that biblical prosperity here did not mean that Joseph was free from adversity. He was still a servant in a foreign land. God’s presence is therefore not measured merely by favorable outward circumstances.

Joseph entrusted with Potiphar’s house

Potiphar himself observed:

“that the LORD was with him, and that the LORD made all that he did to prosper in his hand.”
— Genesis 39:3

Joseph found favor with Potiphar and was made overseer over his house.

The LORD blessed the Egyptian’s house:

“for Joseph’s sake.”
— Genesis 39:5

That is an explicit statement of divine blessing.

Potiphar eventually entrusted virtually everything under Joseph’s care, except for the food he ate.

Joseph’s temptation

Genesis 39:6 describes Joseph as:

“a goodly person, and well favoured.”

Potiphar’s wife then attempted to entice Joseph into adultery.

Joseph refused.

His response reveals several reasons for his refusal. He recognized his master’s trust, recognized that the woman was his master’s wife, and most importantly recognized that the proposed act would be sin against God:

“how then can I do this great wickedness, and sin against God?”
— Genesis 39:9

That is one of the clearest statements in Genesis concerning the Godward nature of sin.

Temptation was not merely momentary:

“she spake to Joseph day by day”
— Genesis 39:10

Joseph nevertheless:

“hearkened not unto her, to lie by her, or to be with her.”

His refusal involved both rejecting the sinful act and refusing unnecessary participation in the compromising situation.

Joseph flees

On a particular day, Joseph entered the house to do his business. Scripture says:

“there was none of the men of the house there within.”
— Genesis 39:11

Potiphar’s wife caught him by his garment.

Joseph:

“left his garment in her hand, and fled, and got him out.”
— Genesis 39:12

He did not remain and attempt to negotiate with temptation. He fled.

This is entirely consistent with the later New Testament command:

“Flee fornication.”
— 1 Corinthians 6:18

Joseph falsely accused

Potiphar’s wife then used Joseph’s garment to support a false accusation against him.

She first spoke to the men of the household and later repeated her accusation to her husband.

Potiphar’s anger was kindled, and Joseph was placed in prison.

Scripture tells us what Potiphar did, but it does not explicitly tell us everything Potiphar privately believed or thought. Claims about whether Potiphar completely believed or doubted his wife would therefore go beyond the text.

The LORD with Joseph in prison

Joseph’s change in circumstances did not change God’s presence:

“But the LORD was with Joseph, and shewed him mercy, and gave him favour in the sight of the keeper of the prison.”
— Genesis 39:21

The keeper committed the prisoners to Joseph’s hand and trusted him with the administration of the prison.

The chapter concludes much as it began:

“because the LORD was with him, and that which he did, the LORD made it to prosper.”
— Genesis 39:23

Joseph went from favored son, to slave, to trusted overseer, to falsely accused prisoner. Yet the repeated certainty of Genesis 39 is not that Joseph understood every circumstance, but that “the LORD was with him.”

• Joseph’s brethren — They hated and envied Joseph and conspired against him.
• Reuben — Sought to prevent Joseph’s death and intended to restore him to his father.
• Judah — Proposed selling Joseph rather than killing him; Genesis 38 then records events in Judah’s own household.
• Tamar — Wife of Er and afterward the central woman in Genesis 38; mother of Pharez and Zarah.
• Er — Judah’s firstborn. Scripture says he “was wicked in the sight of the LORD.”
• Onan — Judah’s second son. His deliberate conduct “displeased the LORD.”
• Shelah — Judah’s third son.
• Hirah the Adullamite — An associate of Judah.
• Daughter of Shuah — Judah’s wife; the KJV does not give her personal name.
• Potiphar — Egyptian officer of Pharaoh, captain of the guard, and Joseph’s master.
• Potiphar’s wife — The KJV does not give her name. She repeatedly tempted Joseph and afterward falsely accused him.
• Keeper of the prison — Entrusted considerable responsibility to Joseph after the LORD gave Joseph favor in his sight.
• Pharez and Zarah — Twin sons of Judah and Tamar; later Scripture explicitly places Pharez in the genealogy of Christ.

Geographic references include the vale of Hebron, Shechem, Dothan, Gilead, Egypt, Adullam, Chezib, and Timnath. Genesis 39 also centers upon Potiphar’s house and the Egyptian prison where the king’s prisoners were confined.

Main Doctrinal or Spiritual Themes

1. Envy and hatred produce destructive fruit

Genesis 37 gives a clear progression in Joseph’s brethren:

“they hated him” — Genesis 37:4
“they hated him yet the more” — Genesis 37:5
“his brethren envied him” — Genesis 37:11
“they conspired against him to slay him” — Genesis 37:18

The text itself establishes the increasing hostility.

The later KJV warning is fitting:

“For where envying and strife is, there is confusion and every evil work.”
— James 3:16

Envy should never be treated as a harmless inward feeling.

2. Sin against another person is ultimately sin against God

Joseph did not reason merely that adultery might damage his reputation or offend Potiphar.

He said:

“how then can I do this great wickedness, and sin against God?”

Biblical morality begins with God’s holiness and authority.

Sin remains sin even when it can apparently be concealed from other men.

3. Sexual purity sometimes requires flight

Joseph’s response was decisive:

“he left his garment in her hand, and fled, and got him out.”

He did not attempt to discover how close he could remain to sin without committing it.

The New Testament gives the same principle plainly:

“Flee fornication.”
— 1 Corinthians 6:18

Separation from temptation is biblical wisdom, not weakness.

4. Faithfulness does not guarantee freedom from false accusation

Joseph did right and nevertheless suffered.

Genesis 39 gives no basis for a theology that says obedience to God always produces immediate comfort, vindication, wealth, or outward success.

Joseph rejected wickedness and was sent to prison.

Yet:

“the LORD was with Joseph.”

A believer’s circumstances are not an infallible measure of God’s favor or presence.

5. The LORD honors faithful stewardship

Joseph was trustworthy both in Potiphar’s house and in prison.

Potiphar:

“made him overseer over his house”
— Genesis 39:4

And the keeper of the prison:

“committed to Joseph’s hand all the prisoners that were in the prison.”
— Genesis 39:22

Joseph’s faithfulness was evident when he possessed little personal freedom and when no earthly promotion was guaranteed.

6. God remains sovereign when men intend evil

Genesis 37 records real human wickedness. Joseph’s brethren were responsible for what they did.

Later, Genesis 50:20 interprets those events without excusing them:

“ye thought evil against me; but God meant it unto good.”

Scripture therefore maintains both truths: men genuinely intended evil, while God sovereignly accomplished good through events they did not control.

This does not mean God approved their hatred or made their evil morally good. Their intent remained “evil.”

7. Human deception cannot overthrow God’s purposes

Joseph’s brethren deceived Jacob. Potiphar’s wife later used Joseph’s garment to support another deception.

In both cases Joseph’s clothing became part of a false account concerning him.

That literary observation is directly visible in the text; however, Scripture does not explicitly identify the two garment incidents as a divinely intended symbolic pattern, so we should not build doctrine upon the similarity.

8. God’s moral standards precede the Mosaic law

Joseph lived before the giving of the law at Sinai, yet he clearly identified adultery as:

“this great wickedness, and sin against God.”

Thus, it would be incorrect to imagine that sexual immorality became wrong only after Moses received the law.

9. God judges wickedness

Genesis 38 states explicitly concerning Er:

“Er…was wicked in the sight of the LORD; and the LORD slew him.”

Concerning Onan:

“the thing which he did displeased the LORD: wherefore he slew him also.”

The chapter therefore presents God as the righteous Judge who sees conduct hidden from other men.

We should not, however, conclude that every premature death or hardship is necessarily a direct judgment for a particular sin unless Scripture itself says so. Genesis 38 says so concerning these two men; that does not authorize us to make the same assertion in cases where God has not revealed it.

10. God’s redemptive purposes are not defeated by deeply flawed families

Genesis 38 contains grave human failure. Nevertheless, later Scripture explicitly includes:

“Phares and Zara of Thamar”

in the genealogy recorded in Matthew 1:3.

This does not excuse anyone’s sin. It demonstrates that human failure cannot frustrate God’s revealed purpose.

Practical Applications or Lessons

Guard the heart against envy

Joseph’s brethren allowed resentment to deepen into hatred and conspiracy. A believer should deal with envy before it bears worse fruit.

“Let us not be desirous of vain glory, provoking one another, envying one another.”
— Galatians 5:26

Be careful about partiality within the home

Genesis 37 explicitly says:

“Israel loved Joseph more than all his children.”

The chapter also explicitly records the brothers’ hostile reaction to that unequal love. Scripture does not directly say in Genesis 37, “Jacob sinned by doing this,” so that specific judgment should not be inserted into the text.

Nevertheless, the account may indicate the serious relational damage that unequal treatment can produce within a family.

Do right when nobody seems to be watching

Joseph’s greatest test occurred when:

“there was none of the men of the house there within.”

His controlling concern was still God:

“how then can I…sin against God?”

Christian character is what a person does under the eye of God, not merely under the observation of men.

Do not negotiate with sexual temptation

Joseph first refused. He continued refusing “day by day.” When physically confronted, he fled.

There are temptations from which the proper biblical response is not extended discussion but separation.

Faithfulness may cost something

Joseph’s obedience cost him his garment, his position, his reputation before Potiphar’s household, and his freedom.

Yet Scripture never suggests he would have been better off yielding to sin.

It is always better to suffer for righteousness than to gain temporary advantage through wickedness.

Do not measure God’s presence by outward ease

Joseph was a slave when:

“the LORD was with Joseph.”

He was also a prisoner when:

“the LORD was with Joseph.”

Hardship does not prove God’s abandonment.

Be trustworthy with whatever responsibility God permits you to have

Joseph was faithful as a servant before he was entrusted with greater responsibility.

He was then faithful as a prisoner before being entrusted with administrative authority there.

The practical principle is consistent with:

“Moreover it is required in stewards, that a man be found faithful.”
— 1 Corinthians 4:2

Recognize that lying often requires further lying

Joseph’s brothers needed a bloodied coat to support their false story.

Potiphar’s wife retained Joseph’s garment and constructed a false account around it.

Sin frequently creates pressure for additional deception.

Remember that God sees the whole story when men do not

Jacob believed Joseph was dead.

Potiphar received a false report concerning Joseph.

Other men therefore acted on incomplete or false information, but the LORD knew the truth throughout.

The believer’s first concern should therefore be faithfulness before God rather than merely maintaining appearances before men.

Overall Message of Genesis 37–39

Genesis 37 shows Joseph rejected by his brethren and carried into Egypt.

Genesis 38 shows serious moral disorder within Judah’s family, while also introducing Pharez, whose later place in the genealogy of Christ is explicitly revealed elsewhere in the KJV.

Genesis 39 shows Joseph maintaining purity and faithfulness in Egypt, first as a servant and then as a prisoner.

Taken together, the chapters teach that human beings can hate, deceive, tempt, falsely accuse, and act wickedly, but they cannot remove God’s knowledge, overturn His sovereignty, or prevent His purposes.

For Joseph personally, the clearest truth in these chapters is not that every circumstance was pleasant or immediately explained. It is this:

“the LORD was with Joseph.”
— Genesis 39:2

And again:

“But the LORD was with Joseph.”
— Genesis 39:21

That is the spiritual center of the account. Joseph’s location changed. His social standing changed. Men’s treatment of him changed. The LORD’s presence did not.
