Lv 16:3-10

3Only in this way may Aaron enter the inner sanctuary. He shall bring a bull of the herd for a purification offering and a ram for a burnt offering. 4He shall wear the sacred linen tunic, with the linen pants underneath, gird himself with the linen sash and put on the linen turban.^c But since these vestments are sacred, he shall not put them on until he has first bathed his body in water.^d 5From the Israelite community he shall receive two male goats for a purification offering and one ram for a burnt offering.

6Aaron shall offer the bull, his purification offering, to make atonement^* for himself and for his household. 7Taking the two male goats and setting them before the LORD at the entrance of the tent of meeting, 8he shall cast lots^e to determine which one is for the LORD and which for Azazel.^{* f} 9The goat that is determined by lot for the LORD, Aaron shall present and offer up as a purification offering. 10But the goat determined by lot for Azazel he shall place before the LORD alive, so that with it he may make atonement by sending it off to Azazel in the desert.
