'Enormous' in the Bible

As I watched, I noticed a windstorm coming from the north -- an enormous cloud, with lightning flashing, such that bright light rimmed it and came from it like glowing amber from the middle of a fire.

For the king of the north will again muster an army, one larger than before. At the end of some years he will advance with a huge army and enormous supplies.

So Jonah went immediately to Nineveh, as the Lord had said. (Now Nineveh was an enormous city -- it required three days to walk through it!)

Should I not be even more concerned about Nineveh, this enormous city? There are more than one hundred twenty thousand people in it who do not know right from wrong, as well as many animals!"
