Leviticus 16:11-13

11“Aaron will bring the bull. He will then slaughter it as his own offering for sin. By doing this he will make peace with the Lord for himself and his family.

12He will take an incense burner full of burning coals from the altar, which is in the Lord’s presence, and two handfuls of finely ground, sweet-smelling incense. He will bring them up to the canopy.

13Then he will put the incense on the fire in the Lord’s presence. The cloud of incense will cover the throne of mercy, which is over the words of God’s promise, so that he will not die.
