Leviticus 14:21

"And if he be poor, and cannot get so much, then he shall take one he-lamb for a trespass-offering to be waved, to make atonement for him, and one tenth part of an ephah of fine flour mingled with oil for a meal-offering, and a log of oil; and two turtle-doves, or two young pigeons, such as he is able to get; and 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 unto the priest, unto the door of the tent of meeting, before Jehovah: and the priest shall take the lamb of the trespass-offering, and the log of oil, and the priest shall wave them for a wave-offering before Jehovah. And he shall kill the lamb of the trespass-offering; and the priest shall take the blood of the trespass-offering, and put it upon the tip of the right ear of him that is to be cleansed, and upon the thumb of his right hand, and upon the great toe of his right foot. And the priest shall pour of the oil into the palm of his own left hand; and the priest shall sprinkle with his right finger some of the oil that is in his left hand seven times before Jehovah: and the priest shall put of the oil that is in his hand upon the tip of the right ear of him that is to be cleansed, and upon the thumb of his right hand, and upon the great toe of his right foot, upon the place of the blood of the trespass-offering: and the rest of the oil that is in the priest's hand he shall put upon the head of him that is to be cleansed, to make atonement for him before Jehovah. And he shall offer one of the turtle-doves, or of the young pigeons, such as he is able to get, even such as he is able to get, the one for a sin-offering, and the other for a burnt-offering, with the meal-offering: and the priest shall make atonement for him that is to be cleansed before Jehovah. This is the law of him in whom is the plague of leprosy, who is not able to get that which pertaineth to his cleansing."

All of these verses are practically nothing more than a recapitulation of Leviticus 14:10-20, with only the substitutions allowed for those too poor to bring what was normally required. For example, a tenth of an ephah was allowed for the poor instead of three tenths, and also the turtle-doves or pigeons instead of lambs. It is important to note, however, that the conditions prior to cleansing were not waived on account of one's poverty. This is important. "The restored Israelite had to realize that not only was sin costly, there was also the type to be demonstrated.[18] This accounts for the fact, "There could be no concessions affecting the main elements of the cleansing, the male lamb for a guilt-offering and the log of oil."[19]
