1 Kings 11:32-36

32but he [and his descendants] shall have one tribe (Benjamin was annexed to Judah), for the sake of My servant David and for the sake of Jerusalem, the city which I have chosen out of all the tribes of Israel—

33because they have abandoned Me and have worshiped Ashtoreth the goddess of the Sidonians, Chemosh the god of the Moabites, and Milcom the god of the sons of Ammon; and they have not walked in My ways and followed My commandments, doing what is right in My sight and keeping My statutes and My ordinances as did his father David.

34However, I will not take the entire kingdom out of his hand; but I will make him ruler all the days of his life for the sake of My servant David, whom I chose because he kept My commandments and My statutes.

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

36Yet to his son I will give one tribe, so that My servant David may have a lamp always before Me in Jerusalem, the city where I have chosen to put My Name and Presence.
