2 Kings 17:27-29

17:27 So the king of Assyria ordered, “Take back one of the priests whom you deported from there. He must settle there and teach them the requirements of the God of the land.” 17:28 So one of the priests whom they had deported from Samaria went back and settled in Bethel. He taught them how to worship the Lord.

17:29 But each of these nations made its own gods and put them in the shrines on the high places that the people of Samaria had made. Each nation did this in the cities where they lived.

2 Kings 17:41

17:41 These nations are worshiping the Lord and at the same time serving their idols; their sons and grandsons do just as their fathers have done, to this very day.
