'Lions' in the Bible

Now when they began to live there, they did not fear the Lord; therefore the Lord sent lions among them which killed some of them.

So the king of Assyria was told, “The nations whom you have sent into exile and settled in the cities of Samaria do not know the custom of the god of the land; so He has sent lions among them, and they are killing them because they do not know the manner of [worship demanded by] the god of the land.”
