1 Kings 11:32-36

32(but he shall have one tribe, for the sake of my servant David and for the sake of Jerusalem, the city that I have chosen out of all the tribes of Israel),

33because they have forsaken me and worshiped Ashtoreth the goddess of the Sidonians, Chemosh the god of Moab, and Milcom the god of the Ammonites, and they have not walked in my ways, doing what is right in my sight and keeping my statutes and my rules, as David his father did.

34Nevertheless, I will not take the whole kingdom out of his hand, but I will make him ruler all the days of his life, for the sake of David my servant whom I chose, who kept my commandments and my statutes.

35But I will take the kingdom out of his son's hand and will give it to you, ten tribes.

36Yet to his son I will give one tribe, that David my servant may always have a lamp before me in Jerusalem, the city where I have chosen to put my name.
