Leviticus 5:10-12

New Revised Standard Version, Anglicised Catholic Edition

¹⁰ And the second he shall offer for a burnt-offering according to the regulation. Thus the priest shall make atonement on your behalf for the sin that you have committed, and you shall be forgiven.

¹¹ But if you cannot afford two turtle-doves or two pigeons, you shall bring as your offering for the sin that you have committed one-tenth of an ephah of choice flour for a sin-offering; you shall not put oil on it or lay frankincense on it, for it is a sin-offering. ¹² You shall bring it to the priest, and the priest shall scoop up a handful of it as its memorial portion, and turn this into smoke on the altar, with the offerings by fire to the Lord; it is a sin-offering.
