“For David is not ascended into the heavens: but he saith himself, The LORD said unto my Lord, Sit thou on my right hand,”
King James Version (KJV)
2:34 Sit thou on my right hand - In this and the following verse is an allusion to two ancient customs; one, to the highest honour that used to be paid to persons by placing them on the right hand, as Solomon did Bathsheba, when sitting on his throne, #1Kings 2:19|; and the other, to the custom of conquerors, who used to tread on the necks of their vanquished enemies, as a token of their entire victory and triumph over them.
Ac 2:34 For. Peter now shows that David had foretold the exaltation of Christ. David . . . saith. See Ps 110:1. Jesus quotes the same passage and applies it to himself (Mt 23:32.). The LORD. God, the Father. My Lord. Christ. Sit thou on my right hand. See Ac 2:33. "To sit at the right hand" implies participation in the Supreme Government.
