'Promised' in the Bible

And he said, “Blessed be the Lord, the God of Israel, who spoke with His mouth to my father David and has fulfilled with His hands what He promised, saying,

Now the Lord has fulfilled His word which He spoke; for I have risen in place of my father David and I sit on the throne of Israel, just as the Lord promised, and have built the house for the Name of the Lord, the God of Israel.

Now therefore, O Lord, the God of Israel, keep with Your servant David, my father, that which You promised him, saying, ‘You shall not fail to have a man to sit on the throne of Israel, provided your sons are careful to walk in My law as you, [David,] have walked before Me.’

Yet the Lord would not destroy the house of David because of the covenant which He had made with David, and because He had promised to give a lamp to him and to his sons forever.
