Matthew Henry Commentary Psalms 45:6-9

"Thy throne, O God, is for ever and ever: A sceptre of equity is the sceptre of thy kingdom. Thou hast loved righteousness, and hated wickedness: Therefore God, thy God, hath anointed thee With the oil of gladness above thy fellows. All thy garments [smell of] myrrh, and aloes, [and] cassia; Out of ivory palaces stringed instruments have made thee glad. Kings` daughters are among thy honorable women: At thy right hand doth stand the queen in gold of Ophir." — Psalms 45:6-9 (ASV)

The throne of this almighty King is established forever. While the Holy Spirit leads Christ's people to look to his cross, he teaches them to see the evil of sin and the beauty of holiness, so that none of them can feel encouragement to continue in sin. The Mediator is God; otherwise, he would have been neither able to do the Mediator's work nor fit to wear the Mediator's crown. God the Father, as his God with respect to his human nature and mediatorial offices, has given him the Holy Spirit without measure.

Thus anointed to be a Prophet, Priest, and King, Christ has pre-eminence in the gladdening gifts and graces of the Spirit, and from his fullness communicates them to his brothers and sisters in human nature. The Spirit is called the oil of gladness because of the delight with which Christ was filled, in carrying on his undertakings. The salvation of sinners is the joy of angels, much more of the Son.

And in proportion as we are conformed to his holy image, we may expect the gladdening gifts and influences of the Comforter. The excellences of the Messiah, the suitableness of his offices, and the sufficiency of his grace seem to be intended by the fragrance of his garments. The church formed of true believers is here compared to the queen whom, by an everlasting covenant, the Lord Jesus has betrothed to himself.

This is the bride, the Lamb's wife, whose graces are compared to fine linen, for their purity; to gold, for their costliness: for just as we owe our redemption to the precious blood of the Son of God, so we also owe our adorning to it.
