Here do I not see JESUS, strongly represented by the high priest? Observe, the garments of Aaron. He is not clothed in his rich glorious vestments on this day; because it was a day of humiliation. He had not on the Ephod with the precious stones; but clean linen only. And did not this represent the SON of GOD, who when he died on the cross, as the sin-offering of his people, laid aside the glories of the GODHEAD, and appeared in the humble garment of mortality. Hebrews 2:16-17.

Leviticus 16:3-4
3 Thus shall Aaron come into the holy place: with a young bullock for a sin offering, and a ram for a burnt offering.
4 He shall put on the holy linen coat, and he shall have the linen breeches upon his flesh, and shall be girded with a linen girdle, and with the linen mitre shall he be attired: these are holy garments; therefore shall he wash his flesh in water, and so put them on.
