New Defender's Study Bible Notes
7:12 thy seed. As with many Old Testament prophecies, this remarkable “Davidic Covenant” has both a near and far application. Solomon was David’s “seed,” and he did “build an house for my name,” but the ultimate fulfillment is in the greater “Son of David,” the Lord Jesus Christ, who was “a son over His own house; whose house are we” (Hebrews 3:6).
7:14 my son. Here is an ancient testimony that this son of David would also be uniquely “the Son of God,” as cited and confirmed in Hebrews 1:5.
7:14 commit iniquity. Christ never committed iniquity, but “He was bruised for our iniquities,” for “the LORD hath laid on Him the iniquity of us all” (Isaiah 53:5,6).
7:15 shall not depart. Saul’s kingdom was completely removed, but David was not. Even though Solomon’s sins resulted in the divided kingdom and ultimately in the Assyrian and Babylonian captivities, the covenant was reconfirmed through Christ, who was made of “the seed of David according to the flesh” (Romans 1:3), entitled legally to David’s throne through Solomon (Matthew 1:6-16) and biologically through Mary, the daughter of Heli (Luke 3:23-31).
7:16 for ever before. As the angel Gabriel promised Mary: “He shall be great, and shall be called the Son of the Highest: and the Lord God shall give unto him the throne of his father David: And He shall reign over the house of Jacob for ever; and of His kingdom there shall be no end” (Luke 1:32-33).
7:24 unto thee for ever. It is evident that David understood these promises of the Davidic covenant to apply specifically to the people of Israel, as well as to himself and his promised son. That being so, it is significant that God said nothing to modify this understanding. It is true that eventually God will indeed give “my Son...the uttermost parts of the earth for thy possession” (Psalm 2:7,8), but He also promised Israel that “David my servant shall be king over them;...And they shall dwell in the land that I have given unto Jacob my servant, wherein your fathers have dwelt;...and my servant David shall be their prince for ever” (Ezekiel 37:24,25). As Gabriel promised Mary: “He shall reign over the house of Jacob for ever” (Luke 1:33).
7:28 thy words be true. David’s prayer is a marvelous example of God-pleasing prayer, that of simply reciting and claiming God’s gracious promises, recognizing first of all that whatever God has said is true, and whatever He has promised, He will do.
