I was set up from everlasting
I, a person, and not a quality; a person, and not a nature; the person of Christ as the Son of God, and not the human nature of Christ, which then did not exist; this phrase designs the ordination and constitution of Christ in his office as Mediator. So the Vulgate Latin version renders it, "I was ordained"; Christ was foreordained to be the Redeemer and Saviour of men, to be the propitiation for their sins, to be the head of the church, and the Judge of the world. It intends likewise his inauguration into his office, and his investiture with it; and because anointing with oil was used in installing persons into the offices of prophet, priest, and king; hence Christ's instalment into his office as Mediator is here expressed by an anointing; for the words may be rendered, "I was anointed" F9; it takes in all that goes to his constitution as Mediator, his call, appointment, and investiture; and the whole of his office, every part and branch of it; and chiefly his kingly office, with reference to which the same word is used ( Psalms 2:6 ) ; and so Gersom paraphrases it,
``and there were given to me power, dominion, and greatness;''all which suppose the eternity of his person; for had he not existed from everlasting, he could not have been set up, and anointed as Mediator, or invested with his office as such; from the beginning, or ever the earth was;
or from the first of the earth, or the original of it; that is, before all time, before the earth or anything was created; this further confirms the eternal existence of Christ's person, the antiquity of his office, the early provision of grace in him as Mediator for his people, and may lead to entertain high and honourable thoughts of him.
