Leviticus 14:21-32

“But if he is poor and cannot afford so much, then he shall take one male lamb for a guilt offering to be waved, to make atonement for him, and a tenth of an ephah of fine flour mixed with oil for a grain offering, and a log of oil; also two turtledoves or two pigeons, whichever he can afford. The one shall be a sin offering and the other a burnt offering. And on the eighth day he shall bring them for his cleansing to the priest, to the entrance of the tent of meeting, before the LORD. And the priest shall take the lamb of the guilt offering and the log of oil, and the priest shall wave them for a wave offering before the LORD. And he shall kill the lamb of the guilt offering. And the priest shall take some of the blood of the guilt offering and put it on the lobe of the right ear of him who is to be cleansed, and on the thumb of his right hand and on the big toe of his right foot. And the priest shall pour some of the oil into the palm of his own left hand, and shall sprinkle with his right finger some of the oil that is in his left hand seven times before the LORD. And the priest shall put some of the oil that is in his hand on the lobe of the right ear of him who is to be cleansed and on the thumb of his right hand and on the big toe of his right foot, in the place where the blood of the guilt offering was put. And the rest of the oil that is in the priest’s hand he shall put on the head of him who is to be cleansed, to make atonement for him before the LORD. And he shall offer, of the turtledoves or pigeons, whichever he can afford, one for a sin offering and the other for a burnt offering, along with a grain offering. And the priest shall make atonement before the LORD for him who is being cleansed. This is the law for him in whom is a case of leprous disease, who cannot afford the offerings for his cleansing.”
