1 Kings 11:9-13

9Now the LORD grew angry with Solomon, because his heart had turned away from the LORD, the God of Israel, who had appeared to him twice. 10Although He had warned Solomon explicitly not to follow other gods, Solomon did not keep the LORD’s command.

11Then 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 tear the kingdom away from you and give it to your servant. 12Nevertheless, for the sake of your father David, I will not do it during your lifetime; I will tear it out of the hand of your son. 13Yet I will not tear the whole kingdom away from him. I will give one tribe to your son for the sake of My servant David and for the sake of Jerusalem, which I have chosen.”
