Nahum is after Jonah. Was this destruction of Ninevah after the revival with Jonah?

Yes. Nahum’s prophecy and Nineveh’s destruction came after Jonah’s revival.

In Jonah, Nineveh repented when Jonah preached:

“And the people of Nineveh believed God…” — Jonah 3:5
“And God saw their works, that they turned from their evil way…” — Jonah 3:10

That was a real revival, and God spared the city at that time.

But later generations in Nineveh returned to wickedness. By Nahum’s day, Nineveh was again marked by violence, lies, robbery, pride, and cruelty:

“Woe to the bloody city! it is all full of lies and robbery…” — Nahum 3:1

So the order is:

1. Jonah preaches to Nineveh.
2. Nineveh repents and is spared.
3. Later, Nineveh returns to wickedness.
4. Nahum prophesies Nineveh’s final judgment.
5. Nineveh is destroyed.

Historically, Jonah likely preached sometime before or during the Assyrian period of strength, while Nahum prophesied later, before Nineveh fell in 612 B.C.

The spiritual lesson is strong: one generation’s repentance does not guarantee the next generation’s obedience. Nineveh had past light, past mercy, and past warning—but later rejected it. That made Nahum’s message even more solemn.
