Leviticus 6:8

He shall bring his trespass offering to Yahweh, a ram without blemish from the flock, according to your estimation, for a trespass offering, to the priest.

The priest shall make atonement for him before Yahweh, and he will be forgiven concerning whatever he does to become guilty.

Command Aaron and his sons, saying, 'This is the law of the burnt offering: the burnt offering shall be on the hearth on the altar all night until the morning; and the fire of the altar shall be kept burning on it.

The priest shall put on his linen garment, and he shall put on his linen breeches upon his body; and he shall remove the ashes from where the fire has consumed the burnt offering on the altar, and he shall put them beside the altar.
