'Promise' in the Bible

so that the Lord may fulfill His promise concerning me, saying, ‘If your sons are careful regarding their way [of life], to walk before Me in truth with all their heart and mind and with all their soul, you shall not fail to have a man (descendant) on the throne of Israel.’

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

“Blessed be the Lord, who has given rest to His people Israel, in accordance with everything that He promised. Not one word has failed of all His good promise, which He spoke through Moses His servant.
