'Teeth' in the Bible

“Suddenly, another beast appeared, a second one, that looked like a bear. It was raised up on one side, with three ribs in its mouth between its teeth. It was told, ‘Get up! Gorge yourself on flesh.’

“While I was watching in the night visions, a fourth beast appeared, frightening and dreadful, and incredibly strong, with large iron teeth. It devoured and crushed, and it trampled with its feet whatever was left. It was different from all the beasts before it, and it had 10 horns.

“Then I wanted to know the true meaning of the fourth beast, the one different from all the others, extremely terrifying, with iron teeth and bronze claws, devouring, crushing, and trampling with its feet whatever was left.
