Psalm 110: session, priesthood, exaltation

And David says again: ‘The Lord said to my Lord: Sit at my right hand, until I make your enemies a footstool for your feet. The Lord will stretch forth from Zion the scepter of your power; rule in the midst of your enemies. With you is the beginning in the day of your power in the splendor of the holy ones; from the womb before the morning star I have begotten you. The Lord has sworn and will not repent: You are a priest forever according to the order of Melchizedek… He will drink from the brook by the way; therefore he will lift up his head.’ (Ps 110:1-7; Heb 5:6; Acts 2:34-35)

By these words he proved that the Christ exists before all things, that he is lord of the Gentiles, and that he executes judgment on all human beings and on the kings who now hate him and persecute his name — for such are his enemies. And by naming him God’s eternal priest he declares that he is immortal. And when he says, ‘He drank from the brook on the way; therefore he will lift up his head,’ he speaks of his glorious exaltation after his incarnation, his lowliness, and his humiliations. (Phil 2:8-9)
