Matthew Henry on 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, Re 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.
