1 Kings 11:4-11

4For it came to pass, when Solomon was old, that his wives turned away his heart after other gods; and his heart was not perfect with Jehovah his God, as was the heart of David his father. 5For Solomon went after Ashtoreth the goddess of the Sidonians, and after Milcom the abomination of the Ammonites. 6And Solomon did that which was evil in the sight of Jehovah, and went not fully after Jehovah, as did David his father. 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. 11Wherefore Jehovah said unto Solomon, Forasmuch as this is done of thee, and thou hast not kept my covenant and my statutes, which I have commanded thee, I will surely rend the kingdom from thee, and will give it to thy servant.
