Leviticus 5:10-12 New English Translation (NET Bible)
10 The second bird he must make a burnt offering according to the standard regulation. So the priest will make atonement on behalf of this person for his sin which he has committed, and he will be forgiven.
11 “‘If he cannot afford two turtledoves or two young pigeons, he must bring as his offering for his sin which he has committed a tenth of an ephah of choice wheat flour for a sin offering. He must not place olive oil on it and he must not put frankincense on it, because it is a sin offering. 12 He must bring it to the priest and the priest must scoop out from it a handful as its memorial portion and offer it up in smoke on the altar on top of the other gifts of the Lord—it is a sin offering.
