Kings III 8:25

25 And now, O Lord God of Israel, keep for thy servant David my father, which thou hast spoken to him, saying, There shall not be taken from thee a man sitting before me on the throne of Israel, provided only thy children shall take heed to their ways, to walk before me as thou hast walked before me.

Kings III 8:25 In-Context

23 and he said, Lord God of Israel, there is no God like thee in heaven above and on the earth beneath, keeping covenant and mercy with thy servant who walks before thee with all his heart;
24 which thou hast kept toward thy servant David my father: for thou hast spoken by thy mouth and thou hast fulfilled it with thine hands, as this day.
25 And now, O Lord God of Israel, keep for thy servant David my father, which thou hast spoken to him, saying, There shall not be taken from thee a man sitting before me on the throne of Israel, provided only thy children shall take heed to their ways, to walk before me as thou hast walked before me.
26 And now, O Lord God of Israel, let, I pray thee, thy word to David my father be confirmed.
27 But will God indeed dwell with men upon the earth? if the heaven and heaven of heavens will not suffice thee, how much less even this house which I have built to thy name?
