Leviticus 14:18-20

New Revised Standard Version, Anglicised

¹⁸ The rest of the oil that is in the priest’s hand he shall put on the head of the one to be cleansed. Then the priest shall make atonement on his behalf before the Lord: ¹⁹ the priest shall offer the sin-offering, to make atonement for the one to be cleansed from his uncleanness. Afterwards he shall slaughter the burnt-offering; ²⁰ and the priest shall offer the burnt-offering and the grain-offering on the altar. Thus the priest shall make atonement on his behalf and he shall be clean.
