2 Kings 17:25, 27-28, 33

And at the beginning of their dwelling there, they did not fear the LORD. Therefore the LORD sent lions among them, which killed some of them.

Then the king of Assyria commanded, “Send there one of the priests whom you carried away from there, and let him go and dwell there and teach them the law of the god of the land.” So one of the priests whom they had carried away from Samaria came and lived in Bethel and taught them how they should fear the LORD.

So they feared the LORD but also served their own gods, after the manner of the nations from among whom they had been carried away.
