Leviticus 5:7-13
5:7 “‘If he cannot afford an animal from the flock, he must bring his penalty for guilt for his sin that he has committed, two turtledoves or two young pigeons, to the Lord, one for a sin offering and one for a burnt offering.
5:8 He must bring them to the priest and present first the one that is for a sin offering. The priest must pinch its head at the nape of its neck, but must not sever the head from the body.
5:9 Then he must sprinkle some of the blood of the sin offering on the wall of the altar, and the remainder of the blood must be squeezed out at the base of the altar – it is a sin offering.
5:10 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.
5:11 “‘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.
5:12 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.
5:13 So the priest will make atonement on his behalf for his sin which he has committed by doing one of these things, and he will be forgiven. The remainder of the offering will belong to the priest like the grain offering.’”
