2 Kings 17:25, 27, 28, 33

When they first lived there, they did not worship the LORD; so he sent lions among them and they killed some of the people.

Then the king of Assyria gave this order: “Have one of the priests you took captive from Samaria go back to live there and teach the people what the god of the land requires.”

So one of the priests who had been exiled from Samaria came to live in Bethel and taught them how to worship the LORD.

They worshiped the LORD, but they also served their own gods in accordance with the customs of the nations from which they had been brought.
