'Great City' in the Bible

Arise, go to Nineveh, that great city, and cry against it; for their wickedness has come up before me.

Arise, go unto Nineveh, that great city, and preach unto it the preaching that I bid you.

So Jonah arose, and went unto Nineveh, according to the word of the LORD. Now Nineveh was an exceedingly great city of three days' journey around it.

And should not I spare Nineveh, that great city, in which are more than sixscore thousand persons that cannot discern between their right hand and their left hand; and also many cattle?
