Then Aaron shall enter the tent of meeting, and shall take off the linen vestments that he put on when he went into the holy place, and shall leave them there. He shall bathe his body in water in a holy place, and put on his vestments; then he shall come out and offer his burnt offering and the burnt offering of the people, making atonement for himself and for the people. The fat of the sin offering he shall turn into smoke on the altar.
