New King James Version

⁴ He shall put the ^(A)holy linen tunic and the linen trousers on his body; he shall be girded with a linen sash, and with the linen turban he shall be attired. These are holy garments. Therefore ^(B)he shall wash his body in water, and put them on. ⁵ And he shall take from ^(C)the congregation of the children of Israel two kids of the goats as a sin offering, and one ram as a burnt offering.

⁶ “Aaron shall offer the bull as a sin offering, which is for himself, and ^(D)make atonement for himself and for his house.
