Leviticus 14:18-20

New Century Version

¹⁸ He will put the rest of the oil that is in his left hand on the head of the person to be made clean. In this way the priest will make that person clean so he can belong to the Lord again.

¹⁹ “Next the priest will offer the sin offering to make that person clean so he can belong to the Lord again. After this the priest will kill the animal for the whole burnt offering, ²⁰ and he will offer the burnt offering and grain offering on the altar. In this way he will make that person clean so he can belong to the Lord again.
