1 Kings 11:31-32

31Then he said to Jeroboam, ‘Take ten pieces for yourself. This is what the Lord, Israel's God, is saying to you: “I will take Solomon's kingdom away from him! I will give you ten tribes to rule over.

32But Solomon will continue to rule over one tribe. That is because King David served me faithfully, and because I have chosen Jerusalem as my special city. I did not choose a city in any of the other tribes of Israel.
