1 Kings 11:4-8

4When Solomon became old, his wives shifted his allegiance to other gods; he was not wholeheartedly devoted to the Lord his God, as his father David had been.

5Solomon worshiped the Sidonian goddess Astarte and the detestable Ammonite god Milcom.

6Solomon did evil in the Lord’s sight; he did not remain loyal to the Lord, like his father David had.

7Furthermore, on the hill east of Jerusalem Solomon built a high place for the detestable Moabite god Chemosh and for the detestable Ammonite god Milcom.

8He built high places for all his foreign wives so they could burn incense and make sacrifices to their gods.
