Leviticus 16:3-17

³Let Aaron come into the holy place in this way: with an ox for a sin-offering and a male sheep for a burned offering.

⁴Let him put on the holy linen coat, and the linen trousers on his body, and the linen band round him, and the linen head-dress on his head; for this is holy clothing, and before he puts them on his body is to be washed with water.

⁵And let him take from the children of Israel two he-goats for a sin-offering and one male sheep for a burned offering.

⁶And Aaron is to give the ox of the sin-offering for himself, to make himself and his house free from sin.

⁷And he is to take the two goats and put them before the Lord at the door of the Tent of meeting.

⁸And Aaron will make selection from the two goats by the decision of the Lord, one goat for the Lord and one for Azazel.

⁹And the goat which is marked out for the Lord, let Aaron give for a sin-offering.

¹⁰But the goat for Azazel is to be placed living before the Lord, for the taking away of sin, that it may be sent away for Azazel into the waste land.

¹¹And Aaron is to give the ox of the sin-offering for himself and take away sin from himself and his house, and put to death the ox of the sin-offering which is for himself.

¹²And he is to take a vessel full of burning coal from the altar before the Lord and in his hand some sweet perfume crushed small, and take it inside the veil;

¹³And let him put the perfume on the fire before the Lord so that the ark may be covered with a cloud of the smoke of the perfume, in order that death may not overtake him.

¹⁴And let him take some of the blood of the ox, shaking drops of it from his finger on the cover of the ark on the east side, and before it, seven times.

¹⁵Then let him put to death the goat of the sin-offering for the people, and take its blood inside the veil and do with it as he did with the blood of the ox, shaking drops of it on and before the cover of the ark.

¹⁶And let him make the holy place free from whatever is unclean among the children of Israel and from their wrongdoing in all their sins; and let him do the same for the Tent of meeting, which has its place among an unclean people.

¹⁷And no man may be in the Tent of meeting from the time when Aaron goes in to take away sin in the holy place till he comes out, having made himself and his house and all the people of Israel free from sin.
