40 For Aaron's sons you shall make tunics and sashes and headdresses; you shall make them for their glorious adornment. 41 You shall put them on your brother Aaron, and on his sons with him, and shall anoint them and ordain them and consecrate them, so that they may serve me as priests. 42 You shall make for them linen undergarments to cover their naked flesh; they shall reach from the hips to the thighs; 43 Aaron and his sons shall wear them when they go into the tent of meeting, or when they come near the altar to minister in the holy place; or they will bring guilt on themselves and die. This shall be a perpetual ordinance for him and for his descendants after him.

Commentary on Exodus 28:40-43

(Read Exodus 28:40-43)

The priest's garments typify the righteousness of Christ. If we appear not before God in that, we shall bear our iniquity, and die. Blessed is he, therefore, that watcheth, and keepeth his garments, Revelation 16:15. And blessed be God that we have a High Priest, appointed of God, and set apart for his work; furnished for his high office by the glory of his Divine majesty, and the beauty of perfect holiness. Happy are we, if by the law spiritually understood, we see that such a High Priest became us; that we cannot draw near to a holy God, or be accepted, but by him. There is no light, no wisdom, no perfection, but from him; no glory, no beauty, but in being like unto him. Let us take encouragement from the power, love, and compassion of our High Priest, to draw near with boldness to the throne of grace, that we may obtain mercy, and find grace to help in time of need.
