'Lions' in the Bible

So it was, at the beginning of their dwelling there, that they didn't fear Yahweh: therefore Yahweh sent lions among them, which killed some of them.

Therefore they spoke to the king of Assyria, saying, "The nations which you have carried away, and placed in the cities of Samaria, don't know the law of the god of the land. Therefore he has sent lions among them, and behold, they kill them, because they don't know the law of the god of the land."
