1 Kings 11:7

3He had seven hundred wives, princesses, and three hundred concubines. His wives turned his heart away.

4When Solomon was old, his wives turned away his heart after other gods; and his heart was not perfect with the LORD his God, as the heart of David his father was.

5For Solomon went after Ashtoreth the goddess of the Sidonians, and after Milcom the abomination of the Ammonites.

6Solomon did that which was evil in the LORD’s sight, and didn’t go fully after the LORD, as David his father did.

7Then Solomon built a high place for Chemosh the abomination of Moab, on the mountain that is before Jerusalem, and for Molech the abomination of the children of Ammon.

8So he did for all his foreign wives, who burned incense and sacrificed to their gods.

9The LORD was angry with Solomon, because his heart was turned away from the LORD, the God of Israel, who had appeared to him twice,

10and had commanded him concerning this thing, that he should not go after other gods; but he didn’t keep that which the LORD commanded.

11Therefore the LORD said to Solomon, “Because this is done by you, and you have not kept my covenant and my statutes, which I have commanded you, I will surely tear the kingdom from you, and will give it to your servant.
