Nineveh was wicked too. Jonah thought they deserved what was coming to them.
But in Jonah chapter 4, God shares a different opinion.
Turns out God made the people in Nineveh. And while God was prepared to destroy Nineveh, he first sent Jonah to convince them to repent. And then he sent a giant fish when Jonah tried to run away.
Never turned out so well for Sodom & Gomorrah did it???
