Jonah 3:1-4

Now the word of the Lord came to Jonah the second time, saying,

“Arise, go to Nineveh, the great city, and proclaim to it the proclamation which I am going to tell you.”

So Jonah got up and went to Nineveh according to the word of the Lord. Now Nineveh was an exceedingly large city, a three days’ walk.

Then Jonah began to go through the city one day’s walk; and he cried out and said, “Forty more days, and Nineveh will be overthrown.”
