2 Kings 17:25, 27-28, 33

And so it was at the beginning of their dwelling there, that they feared not the LORD: therefore the LORD sent lions among them, which slew some of them.

Then the king of Assyria commanded, saying, Carry thither one of the priests whom ye brought from thence; and let them go and dwell there, and let him teach them the manner of the God of the land. Then one of the priests whom they had carried away from Samaria came and dwelt in Beth-el, and taught them how they should fear the LORD.

They feared the LORD, and served their own gods, after the manner of the nations whom they carried away from thence.
