Jonah's Message to Nineveh
1 Now the word of the LORD came to Jonah the second time, saying,
2 "Arise, go to Nineveh, that great city, and preach to it the message that I tell you."
3 So Jonah arose and went to Nineveh, according to the word of the LORD. Now Nineveh was an exceedingly great city, a three-day journey in extent.
4 And Jonah began to enter the city on the first day's walk. Then he cried out and said, "Yet forty days, and Nineveh shall be overthrown!"
• Nineveh, the capital city of the Assyrian Empire, was indeed a very large city, a three-days journey.
• Nineveh was terrified by Jonah’s message and repented for a time (see timeline)
