Clarke's Bible Commentary - Isaiah 22:25
Verse 25. The nail that is fastened] This must be understood of Shebna, as a repetition and confirmation of the sentence above denounced against him. WHAT is said of Eliakim the son of Hilkiah, ver. 20-24, is very remarkable; and the literal meaning is not easy to be understood. From chap. ix. 6, and from Rev. iii. 7, it seems to belong to our Lord alone. The removal of Shebna from being over the treasure of the Lord's house, ver. 19, and the investiture of Eliakim with his robe, girdle, office, and government, ver. 20, &c., probably point out the change of the Jewish priesthood, and the proclaiming of the unchangeable priesthood of Christ. See Psa. cx. 4.
Eliakim signifies The resurrection of the Lord; or, My God, he shall arise.
Hilkiah signifies The Lord my portion or lot. The key of David, shutting and opening, &c., may intend the way of salvation through Christ alone.
For the hope of salvation and eternal life comes only through Eliakim, the resurrection of Jesus Christ from the dead.
It is said, ver. 24, "They shall hang upon him all the glory of his father's house "-for, in Jesus Christ dwells all the fullness of the Godhead bodily; and the offspring and the issue, µyaxaxh hatstseetsaim from axy yatsa, to go out, - the suckers from the root; the sideshoots, the apostles and primitive ministers of his word. The issue, tw[ypxh hatstsephioth, probably means the issue's issue; so the Targum. The grandchildren, all those who believe on the Lord Jesus through their word.
"The nail that is fastened in the sure place shall be removed, "ver. 25, Kimchi refers not to Eliakim, but to Shebna, ver. 17-19. By, "They shall hang upon him all vessels of small quantity and large quantity, "has been understood the dependence of all souls, of all capacities, from the lowest in intellect to the most exalted on the Lord Jesus, as the only saviour of all lost human spirits.
As the literal interpretation of this prophecy has not been found out, we are justified from parallel texts to consider the whole as referring to Jesus Christ, and the government of the Church, and the redemption of the world by him. Nor are there many prophecies which relate to him more clearly than this, taken in the above sense.
