Leviticus 14:21-24

21“But if the cleansed leper is poor and his means are insufficient, then he is to take one lamb as a guilt offering to be waved to make atonement for him, and one tenth of an ephah of fine flour mixed with oil as a grain offering, and a log of oil,

22and two turtledoves or two young pigeons, such as he can afford, one shall be a sin offering, the other a burnt offering.

23He shall bring them on the eighth day for his [ceremonial] cleansing to the priest at the doorway of the Tent of Meeting, before the Lord.

24The priest shall take the lamb of the guilt offering, and the log of oil, and shall present them as a wave offering before the Lord.
