'Promised' in the Bible

And Jehovah hath performed his word that he spake; for I am risen up in the room of David my father, and sit on the throne of Israel, as Jehovah promised, and have built the house for the name of Jehovah, the God of Israel.

Now therefore, O Jehovah, the God of Israel, keep with thy servant David my father that which thou hast promised him, saying, There shall not fail thee a man in my sight to sit on the throne of Israel, if only thy children take heed to their way, to walk in my law as thou hast walked before me.

Howbeit Jehovah would not destroy the house of David, because of the covenant that he had made with David, and as he promised to give a lamp to him and to his children alway.
