1 Kings 11:7-10

7Then did Solomon build a high place for Chemosh the abomination of Moab, in the mount that is before Jerusalem, and for Molech the abomination of the children of Ammon. 8And so did he for all his foreign wives, who burnt incense and sacrificed unto their gods.

9And Jehovah was angry with Solomon, because his heart was turned away from Jehovah, the God of Israel, who had appeared unto him twice, 10and had commanded him concerning this thing, that he should not go after other gods: but he kept not that which Jehovah commanded.
