Leviticus 14:19-22

19The priest shall next offer the 1sin offering and make atonement for the one to be cleansed from his uncleanness. Then afterward, he shall slaughter the burnt offering. 20The priest shall offer up the burnt offering and the grain offering on the altar. Thus the priest shall make atonement for him, and 2he will be clean.

21“3But if he is poor and his 4means are insufficient, then he is to take one male lamb for a 5guilt offering as a wave offering to make atonement for him, and one-tenth of an 6ephah of fine flour mixed with oil for a grain offering, and a 78log of oil, 22and two turtledoves or two young pigeons which 9are within his means, 10the one shall be a 11sin offering and the other a burnt offering.
