Sins and punishment

Jewish scribes say that Solomon's teacher was Shimei ben Gera, and while he lived, he prevented Solomon from marrying foreign wives. The Talmud says at Ber. 8a: "For as long as Shimei the son of Gera was alive Solomon did not marry the daughter of Pharaoh" (see also Midrash Tehillim to Ps. 3:1). Solomon's execution of Shimei was his first descent into sin.

According to 1 Kings 11:4 Solomon's "wives turned his heart after other gods", their own national deities, to whom Solomon built temples, thus incurring divine anger and retribution in the form of the division of the kingdom after Solomon's death (1 Kings 11:9–13). 1 Kings 11 describes Solomon's descent into idolatry, particularly his turning after Ashtoreth, the goddess of the Sidonians, and after Milcom, the god of the Ammonites. In Deuteronomy 17:16–17, a king is commanded not to multiply horses or wives, neither greatly multiply to himself gold or silver. Solomon sinned in all three of these areas. In addition to his wives, he collected 666 talents of gold each year (1 Kings 10:14), a huge amount for a small nation like Israel. He gathered multitudes of horses and chariots from as far as Egypt, and as Deuteronomy 17 warns, took Israel back to Egypt in spirit.

According to 1 Kings 11:30–34 and 1 Kings 11:9–13, it was because of these sins that the Lord punished Solomon by removing most of the tribes of Israel from rule by Solomon's house.

And the Lord was angry with Solomon, because his heart had turned away from the Lord, the God of Israel, who had appeared to him twice and had commanded him concerning this thing, that he should not go after other gods. But he did not keep what the Lord commanded. Therefore the Lord said to Solomon, "Since this has been your practice and you have not kept my covenant and my statutes that I have commanded you, I will surely tear the kingdom from you and will give it to your servant. Yet for the sake of David your father I will not do it in your days, but I will tear it out of the hand of your son. However, I will not tear away all the kingdom, but I will give one tribe to your son, for the sake of David my servant and for the sake of Jerusalem that I have chosen.
