(36) David himself said by the Holy Ghost.--St. Mark is more emphatic in ascribing the words of David to the influence of the Holy Spirit than either St. Matthew, who simply quotes, or St. Luke, who uses the more general phrase "in spirit." (Comp. 2Peter 1:21.)

Verse 36. - The Lord said unto my Lord. From this verse (Psalm 110.) our Lord shows that the Messiah, such as he was, was not a mere man, as the Pharisees thought, but that he was God, and therefore David's Lord. The meaning, therefore, is this, "The Lord God said to my Lord," that is, Christ, "Sit thou at my right hand," that is, when, after his cross, his death, and his resurrection, he will exalt him far above all principality and power, and place him next to him in heaven, that he may reign with supreme happiness and power and glory over all creatures. These words show that this is a Divine decree, fixed and irrevocable. Till I make thine enemies thy footstool (ὑποπόδιον τῶν ποδῶν σου); literally, the footstool of thy feet; that is, reign with me in glory until the day of judgment, when I will make the wicked, all opposing powers, subject to thee. The word "till" does not imply that Christ will then cease to reign. "Of his kingdom there shall be no end." But he will then formally deliver up the kingdom to God, even the Father, only that he may receive it again as the second Person of the Godhead.

12:35-40 When we attend to what the Scriptures declare, as to the person and offices of Christ, we shall be led to confess him as our Lord and God; to obey him as our exalted Redeemer. If the common people hear these things gladly, while the learned and distinguished oppose, the former are happy, and the latter to be pitied. And as sin, disguised with a show of piety, is double iniquity, so its doom will be doubly heavy.For David himself said by the Holy Ghost,.... In Psalm 110:1, being inspired by the Spirit of God:

the Lord said to my Lord, sit thou on my right hand, till I make thine enemies thy footstool. This is a proof, that David did call Christ his Lord; and that he called him so in spirit; since these words were delivered by him under the inspiration of the Holy Spirit: that the psalm was wrote by David, the title shows; and that he spake it as he was influenced by the Holy Ghost, our Lord declares: the passage relates to what God the Father said to Christ, when being risen from the dead, he ascended on high, and entered into the most holy place; he bid him sit down at his right hand, as having done the work of man's salvation, he was sent about, to full satisfaction; and as a mark of affection to him, and honour conferred upon him in the human nature; where he should continue, till all his enemies, Jews, Pagans, Papists, and Mahometans, as well as Satan, and all his principalities and powers, were so subdued under him, as to be as a footstool to his throne: and when David prophetically speaks of this, he calls the Messiah his Lord; saying, the "Lord said to my Lord"; on which account the prophecy is cited; who was so, as he is God, and his Creator and Redeemer. That this prophecy is a prophecy of the Messiah, and is applicable to no other but he; and is therefore pertinently cited, and applied to him here; see Gill on Matthew 22:44.
