'Great City' in the Bible

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

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

So Jonah arose, and went unto Nineveh, according to the word of Jehovah. Now Nineveh was an exceeding great city, of three days journey.

and should not I have regard for Nineveh, that great city, wherein are more than sixscore thousand persons that cannot discern between their right hand and their left hand; and also much cattle?
