'Promised' in the Bible

"Yahweh has performed his word that he spoke; for I have risen up in the place of David my father, and sit on the throne of Israel, as Yahweh promised, and have built the house for the name of Yahweh, the God of Israel.

who have kept with your servant David my father that which you promised him: yes, you spoke with your mouth, and have fulfilled it with your hand, as it is this day.

"Now therefore, Yahweh, the God of Israel, keep with your servant David my father that which you have promised him, saying, 'There shall not fail you a man in my sight to sit on the throne of Israel, if only your children take heed to their way, to walk in my law as you have walked before me.'

However Yahweh 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 always.
