'Great City' in the Bible

“Go to Nineveh, that great city, and proclaim [judgment] against it, for their wickedness has come up before Me.”

“Go to Nineveh the great city and declare to it the message which I am going to tell you.”

So Jonah went to Nineveh in accordance with the word of the Lord. Now Nineveh was an exceedingly great city, a three days’ walk [about sixty miles in circumference].

Should I not have compassion on Nineveh, the great city in which there are more than 120,000 [innocent] persons, who do not know the difference between their right and left hand [and are not yet accountable for sin], as well as many [blameless] animals?”
