2 Kings 17:7-11

Now this came about because the sons of Israel had sinned against the Lord their God, who had brought them up from the land of Egypt, from under the hand of Pharaoh, king of Egypt; and they had feared other gods.

They also followed the customs of the nations whom the Lord had driven out from the sons of Israel, and in the customs of the kings of Israel which they had introduced.

And the sons of Israel did things secretly against the Lord their God which were not right. Moreover, they built for themselves high places in all their towns, from watchtower to fortified city.

And they set up for themselves memorial stones and Asherim on every high hill and under every green tree,

and there they burned incense on all the high places as the nations did that the Lord had taken into exile before them; and they did evil things, provoking the Lord.
