Jonah 1:2

Arise, go to Nineveh, that great city, and cry against it, by preaching a call to repentance; for their wickedness is come up before Me, as had that of Sodom and Gomorrah hundreds of years before. Cf Genesis 18:20. The name Nineveh was applied to a complex of four ancient cities, including Nineveh proper, which lay between the Tigris River and a low range of hills, about 500 miles northeast of Jerusalem. The entire length of the compound city was about twenty-five miles, while its breadth was fifteen. At that time it had more than half a million inhabitants and was the capital and metropolis of the entire heathen world.
