Messianic Prophecy: "I have made a covenant with my chosen one, I have sworn to David my servant, 'I will establish your line forever and make your throne firm through all generations.' ... He will call out to me, 'You are my Father, my God, the Rock my Savior.' I will also appoint him my firstborn, the most exalted of the kings of the earth. I will maintain my love to him forever, and my covenant with him will never fail" (Psalm 89:3,4,26-28).

Fulfillment: Jesus is in David's lineage or line of descendants (Matthew 1:1,6,16). After He returns back to earth, He will reign forever and ever (Revelation 11:15,17). Jesus was the only begotten Son of God the Father (John 3:16).
