المزامير ١١٠:٤

This psalm is pure gospel; it is only, and wholly, concerning Christ, the Messiah promised to the fathers and expected by them. It is plain that the Jews of old, even the worst of them, so understood it, however the modern Jews have endeavoured to pervert it and to rob us of it; for when the Lord Jesus proposed a question to the Pharisees upon the first words of this psalm, where he takes it for granted that David, in spirit, calls Christ his Lord though he was his Son, they chose rather to say nothing, and to own themselves gravelled, than to make it a question whether David does indeed speak of the Messiah or no; for they freely yield so plain a truth, though they foresee it will turn to their own disgrace, Mat 22:41, etc. Of him therefore, no doubt, the prophet here speaks of him and of no other man. Christ, as our Redeemer, executes the office of a prophet, of a priest, and of a king, with reference both to his humiliation and his exaltation; and of each of these we have here an account. I. His prophetical office (Psa 110:2). II. His priestly office (Psa 110:4). III. His kingly office (Psa 110:1, Psa 110:3, Psa 110:5, Psa 110:6). IV. His estates of humiliation and exaltation (Psa 110:7). In singing this psalm we must act faith upon Christ, submit ourselves entirely to him, to his grace and government, and triumph in him as our prophet, priest, and king, by whom we hope to be ruled, and taught, and saved, for ever, and as the prophet, priest, and king, of the whole church, who shall reign till he has put down all opposing rule, principality, and power, and delivered up the kingdom to God the Father. A psalm of David.

110:4 The Lord had made an unbreakable oath and covenant, so his apparent rejection of David’s dynasty (89:38) in the Exile had led to a crisis. The placement of Ps 110 in Book Five reaffirms the future of the dynasty: David’s descendant must conform to God’s standard of integrity (Ps 101). His ministry will be transformed as he serves under God’s kingship (Pss 93–100). • You are a priest forever: The role of God’s messianic ruler changes. The priestly kingship of David and his descendants extended to serving as patrons of the Temple. David had the Ark brought to Jerusalem (2 Sam 6:15) and arranged for the Temple service (1 Chr 6:31-48; 15:11-26; 16:4-42; 23:4-32; 25:1). Solomon supervised the Temple construction (1 Kgs 5:1–7:51). Even so, Israel’s kingship was separate from its priesthood. In the messianic kingdom, the king would also minister as priest, as Melchizedek, king of Salem (Gen 14:18), had done. The New Testament develops the ministry of Jesus Christ as a fulfillment of this new order (see Heb 5:6-10; 6:20–7:25).
