2 Kings 17:9-11

9The people of Israel had also secretly done many things that were not pleasing to the Lord their God. They built pagan shrines for themselves in all their towns, from the smallest outpost to the largest walled city.

10They set up sacred pillars and Asherah poles at the top of every hill and under every green tree.

11They offered sacrifices on all the hilltops, just like the nations the Lord had driven from the land ahead of them. So the people of Israel had done many evil things, arousing the Lord’s anger.
