1 Kings 11:7-10

7Then Solomon built a high place for [worshiping] Chemosh the horror (detestable idol) of Moab, on the hill which is east of Jerusalem, and for Molech the horror (detestable idol) of the sons of Ammon.

8And he did the same for all of his foreign wives, who burned incense and sacrificed to their gods.

9So the Lord became 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 follow other gods; but he did not observe (remember, obey) what the Lord had commanded.
