Leviticus 5:10-12 New American Bible (Revised Edition) (NABRE)
10 The other bird he shall offer as a burnt offering according to procedure. Thus the priest shall make atonement on the person’s behalf for the wrong committed, so that the individual may be forgiven.
11 If the person is unable to afford even two turtledoves or two pigeons, that person shall bring as an offering for the wrong committed one tenth of an ephah[a] of bran flour for a purification offering. The guilty party shall not put oil or place frankincense on it, because it is a purification offering. 12 The individual shall bring it to the priest, who shall take a handful as a token of the offering and burn it on the altar with the other oblations for the Lord. It is a purification offering.
