Kings III 8:24

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.

Kings III 8:24 In-Context

22 And Solomon stood up in front of the altar before all the congregation of Israel; and he spread out his hands toward heaven:
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.
