Leviticus 5:11-13

‘But if he is not able to bring two turtledoves or two young pigeons, then he who sinned shall bring for his offering one-tenth of an ephah of fine flour as a sin offering. He shall put no oil on it, nor shall he put frankincense on it, for it is a sin offering. Then he shall bring it to the priest, and the priest shall take his handful of it as a memorial portion, and burn it on the altar according to the offerings made by fire to the LORD. It is a sin offering. The priest shall make atonement for him, for his sin that he has committed in any of these matters; and it shall be forgiven him. The rest shall be the priest’s as a grain offering.’ ”
