2 Kings 17:27-29

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. Nevertheless, each national group made its own gods in the several towns where they settled, and set them up in the shrines the people of Samaria had made at the high places.
