Psalms 110
Confitebor tibi, Domine. God is to be praised for his graces, and benefits to his church. Alleluia.
1.1 'The Lord said to my Lord: Sit thou at my right hand'—Jesus uses this verse to demonstrate the Messiah's divinity (Matt 22:41-46).
1.2 If David calls the Messiah 'Lord,' the Messiah cannot be merely David's human descendant; He must be divine.
1.3 This is the most quoted OT verse in the NT, applied to Christ's exaltation and session at the Father's right hand.
4.1 'Thou art a priest for ever according to the order of Melchisedech'—the Messiah is both king (v. 1) and priest, but not of the Levitical order.
4.2 Hebrews develops this: Christ's eternal priesthood supersedes the Aaronic priesthood. He offers His own sacrifice once for all.
