Leviticus 14:19-22

19Next the priest shall offer the sin offering and make atonement for the one to be cleansed from his uncleanness, and afterward kill the burnt offering.

20The priest shall offer the burnt offering and the grain offering on the altar; and the priest shall make atonement for him, and he shall be clean.

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.
