John Wesley on Psalms 110:1

The Lord - God the father. Said - Decreed it from eternity, and in due time published this decree, and actually executed it; which he did when he raised up Christ from the dead, and brought him into his heavenly mansion. Unto - Unto his son the Messiah, whom David designedly calls his Lord, to admonish the whole church, that although he was his son according to his human nature, yet he had an higher nature, and was also his Lord, as being God blessed for ever, and consequently Lord of all things. The Hebrew word Adon is one of God's titles, signifying his power and authority over all things, and therefore is most fitly given to the Messiah, to whom God hath delegated all his power Matt 28:18. Sit - Now take thy rest and the possession of that sovereign kingdom and glory, which by right belongeth to thee; do thou rule with me with equal power and majesty, as thou art God; and with an authority and honour far above all creatures, as thou art man. Make - By my almighty power communicated to thee as God by eternal generation, and vouchsafed to thee as mediator. Enemies - All ungodly men, sin and death, and the devil. Footstool - Thy slaves and vassals.
