When Solomon was old, his wives seduced him [to follow] other gods. His heart was not completely with the LORD his God, as his father David's heart had been.
Solomon followed Ashtoreth, the goddess of the Sidonians, and Milcom, the detestable idol of the Ammonites.
Solomon did what was evil in the LORD's sight, and unlike his father David, he did not completely follow the LORD.
At that time, Solomon built a high place for Chemosh, the detestable idol of Moab, and for Milcom, the detestable idol of the Ammonites on the hill across from Jerusalem.
He did the same for all his foreign wives, who were burning incense and offering sacrifices to their gods.
The LORD was angry with Solomon, because his heart had turned away from the LORD God of Israel, who had appeared to him twice.
He had commanded him about this, so that he would not follow other gods, but Solomon did not do what the LORD had commanded.
