Leviticus 6:7-12

⁷This is how the priest will make you right before the Lord, and you will be forgiven whatever sins you may have done that you are guilty of.”

⁸The Lord told Moses,

⁹“Give Aaron and his sons these instructions regarding the burnt offering: The burnt offering is to be left on the fireplace of the altar throughout night until morning, and the fire must be kept burning on the altar.

¹⁰The priest shall put on his linen clothes and underwear, and he shall take from the altar the greasy ashes of the burnt offering that the fire has burned up and set them down beside the altar.

¹¹Then he has to change his clothes, and take the ashes outside the camp to a place that's ceremonially clean.

¹²The fire on the altar must be kept burning—don't let it go out. Each morning the priest is to add wood to the fire, carefully place the burnt offering on it, and burn the fat parts of the peace offerings on it.
