'Great' in the Bible

“Get up! Go to the great city of Nineveh and preach against it, because their wickedness has confronted Me.”

Now the Lord had appointed a huge fish to swallow Jonah, and Jonah was in the fish three days and three nights.

“Get up! Go to the great city of Nineveh and preach the message that I tell you.”

Should I not care about the great city of Nineveh, which has more than 120,000 people who cannot distinguish between their right and their left, as well as many animals?”
