18The rest of the oil in his palm, the priest is to put on the head of the one to be cleansed, to make atonement for him before the LORD.
19Then the priest is to sacrifice the sin offering and make atonement for the one to be cleansed from his uncleanness. After that, the priest shall slaughter the burnt offering
20and offer it on the altar, with the grain offering, to make atonement for him, and he will be clean.
— Leviticus 14:18-20
