'City' in the Bible

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

"Arise, go to Nineveh, that great city, and preach to it the message that I give you."

So Jonah arose, and went to Nineveh, according to the word of Yahweh. Now Nineveh was an exceedingly great city, three days' journey across.

Jonah began to enter into the city a day's journey, and he cried out, and said, "In forty days, Nineveh will be overthrown!"

Then Jonah went out of the city, and sat on the east side of the city, and there made himself a booth, and sat under it in the shade, until he might see what would become of the city.

Shouldn't I be concerned for Nineveh, that great city, in which are more than one hundred twenty thousand persons who can't discern between their right hand and their left hand; and also much livestock?"
