Over and over in the gospels, people cry out to Jesus, “Have mercy on us, you son of David!”
Why is the Messiah’s title as David’s son the one that blind men and a Canaanite woman latched on to as they asked for healing? (Matt. 9:27; 15:22; 20:30-31; Mark 10:46-48; Luke 18:35-39). Why did the people shout, “Hosanna to the son of David!” when Jesus entered Jerusalem, and why did that make the chief priests and the scribes so indignant? (Matt. 21:9, 15; Mark 11:10). What is the significance of this title?
It would be easy to gloss over Jesus’ title as David’s son, simply taking it as fulfillment of a few prophecies that said Messiah (the Hebrew equivalent to “Christ,” which means “anointed”) would come from King David’s descendants. But the Biblical writers treat this as a highly significant fact, and I think it’s worth looking into more closely.
Fulling A Covenant Promise
I’ve talked about the covenant aspect of Jesus being descended from David in several posts already, including “Inheriting Covenants.” The Lord made a covenant with David that He would establish his offspring’s kingdom forever, and that connected with the promise of Messiah (2 Sam. 7:12-15).
Yahweh has sworn to David in truth. He will not turn from it: “I will set the fruit of your body on your throne. If your children will keep my covenant, my testimony that I will teach them, their children also will sit on your throne forever more.” (Ps. 132:11-12, all verses from WEB translation)
David’s descendants eventually fell into disobedience and lost the physical kingdoms of Israel and Judah. But Jesus — a sinless, obedient son of David — inherited the covenant promise. According to Peter, David actually knew that would be the end result of God’s promises to him about his descendants. Read more
