Leviticus 14:21 -14:32
If, however, he is poor and his means are insufficient, he shall take one male lamb for a guilt offering, to be elevated in expiation for him, one-tenth of a measure of choice flour with oil mixed in for a meal offering, and a log of oil; and two turtledoves or two pigeons, depending on his means, the one to be the sin offering and the other the burnt offering. On the eighth day of his cleansing he shall bring them to the priest at the entrance of the Tent of Meeting, before the Lord. The priest shall take the lamb of guilt offering and the log of oil, and elevate them as an elevation offering before the Lord.
When the lamb of guilt offering has been slaughtered, the priest shall take some of the blood of the guilt offering and put it on the ridge of the right ear of the one being cleansed, on the thumb of his right hand, and on the big toe of his right foot. The priest shall then pour some of the oil into the palm of his own left hand, and with the finger of his right hand the priest shall sprinkle some of the oil that is in the palm of his left hand seven times before the Lord. Some of the oil in his palm shall be put by the priest on the ridge of the right ear of the one being cleansed, on the thumb of his right hand, and on the big toe of his right foot, over the same places as the blood of the guilt offering; and what is left of the oil in his palm the priest shall put on the head of the one being cleansed, to make expiation for him before the Lord. He shall then offer one of the turtledoves or pigeons, depending on his means--whichever he can afford--the one as a sin offering and the other as a burnt offering, together with the meal offering. Thus the priest shall make expiation before the Lord for the one being cleansed. Such is the ritual for him who has a scaly affection and whose means for his cleansing are limited.
