1 Kings 11:9-13

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.

11Therefore the Lord said to Solomon, “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.

12However, 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).

13However, 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.”
