'Lions' in the Bible

and it cometh to pass, at the commencement of their dwelling there, they have not feared Jehovah, and Jehovah doth send among them the lions, and they are destroying among them.

And they speak to the king of Asshur, saying, 'The nations that thou hast removed, and dost place in the cities of Samaria, have not known the custom of the God of the land, and He sendeth among them the lions, and lo, they are destroying them, as they do not know the custom of the God of the land.'
