Jonah 3:2-4 King James Version (KJV)
2 Arise, go unto Nineveh, that great city, and preach unto it the preaching that I bid thee.
3 So Jonah arose, and went unto Nineveh, according to the word of the Lord. Now Nineveh was an exceeding great city of three days' journey.
4 And Jonah began to enter into the city a day's journey, and he cried, and said, Yet forty days, and Nineveh shall be overthrown.
