Leviticus 5:10-13

¹⁰And he shall make the second a whole burnt offering, as it is fit; and the priest shall make atonement for his sin which he has sinned, and it shall be forgiven him.

¹¹And if he cannot afford a pair of turtledoves, or two young pigeons, then shall he bring as his gift for his sin, the tenth part of an ephah of fine flour for a sin offering; he shall not pour oil upon it, nor shall he put frankincense upon it, because it is a sin offering.

¹²And he shall bring it to the priest; and the priest having taken a handful of it, shall lay the memorial of it on the altar of whole burnt offerings to the Lord; it is a sin offering.

¹³And the priest shall make atonement for him for his sin, which he has sinned in one of these things, and it shall be forgiven him; and that which is left shall be the priest’s, as an offering of fine flour.
