King David is the legendary king of Israel spoken of in Scripture as being the forefather of Jesus Christ through the lineage of His mother Mary mentioned in Luke chapter 3. (The royal lineage mentioned in Matthew chapter 1 produced Joseph, the husband of Mary and the stepfather of Jesus.) The Jews expected the Messiah to come from the Davidic lineage. In the book "Kingdom Come", David served as a prince over Israel and also visited the Children Of The Tribulation school to tell of his exploits, particularly that of felling Goliath the giant with only a stone and a sling. At the last day of the Millennial Kingdom, King David confronted Satan after the defeat of his army at the final insurrection just before he would be sent into the Lake of Fire, proclaiming that every knee shall bow and every tongue shall confess that Jesus Christ is Lord to the glory of God the Father.
