2 Kings 17:24-27

24The king of Assyria brought men from Babylon and from Cuthah and from Avva and from Hamath and Sepharvaim, and settled them in the cities of Samaria in place of the sons (people) of Israel. They took possession of Samaria and lived in its cities.

25Now when they began to live there, they did not fear the Lord; therefore the Lord sent lions among them which killed some of them.

26So 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.”

27Then the king of Assyria commanded, “Take back [to Samaria] one of the priests whom you brought from there, and have him go and live there; and have him teach the people the custom of the god of the land.”
