2 Kings 17:9-11

9The Israelites secretly did things against the LORD their God that were not right. From watchtower to fortified city, they built high places in all their cities. 10They set up for themselves sacred pillars and Asherah poles on every high hill and under every green tree. 11They burned incense on all the high places like the nations that the LORD had driven out before them. They did wicked things, provoking the LORD to anger.
