Kings III 11:11 In-Context

9 And the Lord was angry with Solomon, because he turned away his heart from the Lord God of Israel, who had appeared twice to him,
10 and charged him concerning this matter, by no means to go after other gods, but to take heed to do what the Lord God commanded him; neither was his heart perfect with the Lord, according to the heart of David his father.
11 And the Lord said to Solomon, Because it has been thus with thee, and thou hast not kept my commandments and my ordinances which I commanded thee, I will surely rend thy kingdom out of thy hand, and give it to thy servant.
12 Only in thy days I will not do it for David thy father's sake: I will take it out of the hand of thy son.
13 Only I will not take away the whole kingdom: I will give one tribe to thy son for David my servant's sake, and for the sake of Jerusalem, the city which I have chosen.
