exodus 39

Exodus 39:1:
Of the blue, purple, and scarlet thread they made garments of ministry, for ministering in the holy place, and made the holy garments for Aaron, as the Lord had commanded Moses.​

​ 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. --Matthew Henrys

​ Jarchi observes that there is no mention made of linen, because these were not the priestly garments in which there was linen; but these were they with which they covered the vessels of the sanctuary when they journeyed; and so says Aben Ezra; and those were covered with cloths of blue, purple, and scarlet, ( Numbers 4:5-15 ) though some think these were clothes wore by the priests: --John Gills exposition of the Entire Bible
