A Shadow of Christ's Priesthood
Commentators do not focus on the specific action of this verse, but on the priestly garments as a whole. Matthew Henry explains that these rich garments were 'shadows of good things to come,' with the ultimate substance being Christ. As our great High Priest, Jesus took God's people near his heart—symbolized by the breastplate—and consecrated his entire redemptive work to the Father, fulfilling the purpose prefigured by these sacred items.
