King Solomon of Israel possessed seven hundred wives, princesses, and three hundred concubines (1 Kings 11:3 (AMP)). Naamah, the mother of Solomon's son and heir Rehoboam, is the only wife whose name is documented in the Bible.
Solomon loved and had a weakness for foreign women. Among them were Moabites, Ammonites, Edomites, Sidonian (Phoenicians), and Hittites – peoples that the Lord forbade the Israelites to marry. Solomon also married a daughter of the Pharaoh. These wives led Solomon astray: Solomon began worshiping and building alters to the idols of his wives.
This displeased God, and God punished Solomon by having Solomon's kingdom become divided after his death.
Because you have done this and have not kept My covenant and My statutes, which I have commanded you, I will certainly tear the kingdom away from you and give it to your servant. However, I will not do it in your lifetime, for the sake of your father David, but I will tear it out of the hand of your son (Rehoboam). However, I will not tear away all the kingdom; I will give one tribe (Judah) to your son for the sake of My servant David and for the sake of Jerusalem which I have chosen.— 1 Kings 11:11–11:13 (AMP)
