1 Kings 11: 4 - 13
4 For when Solomon was old his wives turned away his heart after other gods; and his heart was not wholly true to the LORD his God, as was the heart of David his father.
5 For Solomon went after Ash'toreth the goddess of the Sido'nians, and after Milcom the abomination of the Ammonites.
6 So Solomon did what was evil in the sight of the LORD, and did not wholly follow the LORD, as David his father had done.
7 Then Solomon built a high place for Chemosh the abomination of Moab, and for Molech the abomination of the Ammonites, on the mountain east of Jerusalem.
8 And so he did for all his foreign wives, who burned incense and sacrificed to their gods.
9 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,
10 and had commanded him concerning this thing, that he should not go after other gods; but he did not keep what the LORD commanded.
11 Therefore the LORD said to Solomon, "Since this has been your mind and you have not kept my covenant and my statutes which I have commanded you, I will surely tear the kingdom from you and will give it to your servant.
12 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.
13 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 which I have chosen."
