Matthew 22:44

“The Lord said to my Lord, You sit on my right hand, until I put your enemies underneath your feet?”

He then amplifies that further by citing the Psalm. On Jesus' interpretation the LORD (YHWH) had said to David's Lord, “You sit on my right hand, until I put your enemies underneath your feet?” To be placed on the right hand was to be given supreme honour (compare Psalms 45:9; Psalms 80:17. See also Mark 16:19; Luke 22:69; Acts 7:56; Hebrews 1:3). It was a position regularly reserved for the King's heir apparent or the prince regent, or failing him the highest ranking person at the court. The Messiah was thus to be supremely honoured by God and vested with His authority (compare Matthew 26:64 where the same Psalm is in mind, and see Matthew 28:18). To have all enemies put under His feet indicated total victory over all His enemies. Thus the Messiah was to be totally supreme enjoying the very authority of God Himself, and acting in His Name (Matthew 28:18).
