2 Kings 17:27-29

Then the king of Assyria commanded, “Send back one of the priests you took away. Let him live there and teach the people what the god wants.” So one of the priests who had been carried away from Samaria returned to live in Bethel. And he taught the people how to honor the LORD. But each nation made gods of its own and put them in the cities where they lived and in the temples where gods were worshiped. These temples had been built by the Samaritans.
