²⁸And the priest shall put of the oil that is on his hand on the tip of the right ear of him that is under purification, and on the thumb of his right hand, and on the great toe of his right foot, on the place of the blood of the trespass offering.

²⁹And that which is left of the oil which is on the hand of the priest he shall put on the head of him that is purged, and the priest shall make atonement for him before the Lord.

³⁰And he shall offer one of the turtledoves or of the young pigeons, as he can afford it,

³²This is the law for him in whom is the plague of leprosy, and who cannot afford the offerings for his purification.

³³And the Lord spoke to Moses and Aaron, saying,

³⁴Whensoever ye shall enter into the land of the Canaanites, which I give you for a possession, and I shall put the plague of leprosy in the houses of the land of your possession;
