1 Kings 11:12-13; 1 Kings 11:32

12 Nevertheless, for the sake of David your father, I will not do it during your lifetime. I will tear it out of the hand of your son. 13 Yet I will not tear the whole kingdom from him, but will give him one tribe for the sake of David my servant and for the sake of Jerusalem, which I have chosen."
32 But for the sake of my servant David and the city of Jerusalem, which I have chosen out of all the tribes of Israel, he will have one tribe.
