Leviticus 5:10-12 Modern English Version (MEV)
10 But the second he shall treat as a burnt offering according to the regulation. The priest shall make atonement for him for his sin that he committed, and he shall be forgiven.
11 But if he cannot afford to bring two turtledoves or two pigeons, he shall bring for his offering for the sin that he committed one-tenth of an ephah[a] of wheat flour for a sin offering. He shall not place olive oil on it, nor shall he put frankincense on it, for it is a sin offering. 12 Then he shall bring it to the priest, and the priest shall scoop out a handful from it as a memorial portion and burn it on the altar as a food offering to the Lord made by fire. It is a sin offering.
