Leviticus 14:19-22

19The priest shall next offer the 12sin 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. So the priest shall make atonement for him, and 3he will be clean.

21“4But if he is poor and his 5means are insufficient, then he is to take one male lamb for a 6guilt offering as a wave offering to make atonement for him, and a tenth of an 7ephah of fine flour mixed with oil as a grain offering, and a 89log of oil, 22and two turtledoves or two young doves, which 10are within his means. 11The one shall be a 1213sin offering, and the other a burnt offering.
