12 Then he will fill up an incense burner with burning coals from the altar that is before the Lord, and with his hands full of finely ground sweet-smelling incense, take them behind the veil. 13 In the presence of the Lord he will put the incense on the burning coals, and the smoke from the incense will cover the atonement cover above the Testimony,16:13. The "Testimony" refers to the two tablets of the Ten Commandments within the Ark. so that he will not die. 14 He will take some of the bull’s blood and with his finger sprinkle it on the east side of the atonement cover. He shall also sprinkle some of it with his finger seven times in front of the atonement cover.
15 Then Aaron will slaughter the goat for the sin offering for the people and bring its blood behind the veil, and with its blood he must do as he did with the bull’s blood. He is to sprinkle it against the atonement cover and in front of it.
34 This regulation applies to you for all time: once a year the Israelites have all their sins made right." Moses did everything as the Lord had ordered.
