The priests' garments were rich and splendid. The church in its infancy was thus taught by shadows of good things to come; but the substance is Christ, and the grace of the gospel. Christ is our great High Priest.
When he undertook the work of our redemption, he put on the clothes of service, he arrayed himself with the gifts and graces of the Spirit, girded himself with resolution to go through the undertaking, took charge of all God's spiritual Israel, laid them near his heart, engraved them on the palms of his hands, and presented them to his Father.
And he crowned himself with holiness to the Lord, consecrating his whole undertaking to the honour of his Father's holiness. True believers are spiritual priests. The clean linen with which all their clothes of service must be made, is the righteousness of saints, Re 19:8.
