Leviticus 14:20-24

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

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

and two turtledoves or two young doves, which are within his means. The one shall be a sin offering, and the other a burnt offering.

Then on the eighth day he shall bring them for his cleansing to the priest, at the doorway of the tent of meeting, before the Lord.

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