Leviticus 5:2-13

2Or if someone touches anything unclean  — a carcass of an unclean wild animal, or unclean livestock, or an unclean swarming creature  — without being aware of it, he is unclean and incurs guilt.

3Or if he touches human uncleanness  — any uncleanness by which one can become defiled  — without being aware of it, but later recognizes it, he incurs guilt.

4Or if someone swears rashly to do what is good or evil — concerning anything a person may speak rashly in an oath — without being aware of it, but later recognizes it, he incurs guilt in such an instance.

5If someone incurs guilt in one of these cases, he is to confess he has committed that sin.

6He must bring his penalty for guilt for the sin he has committed to the Lord: a female lamb or goat from the flock as a sin offering. In this way the priest will make atonement on his behalf for his sin.

7“But if he cannot afford an animal from the flock, then he may bring to the Lord two turtledoves or two young pigeons as penalty for guilt for his sin — one as a sin offering and the other as a burnt offering.

8He is to bring them to the priest, who will first present the one for the sin offering. He is to twist its head at the back of the neck without severing it.

9Then he will sprinkle some of the blood of the sin offering on the side of the altar, while the rest of the blood is to be drained out at the base of the altar; it is a sin offering.

10He will prepare the second bird as a burnt offering according to the regulation. In this way the priest will make atonement on his behalf for the sin he has committed, and he will be forgiven.

11“But if he cannot afford two turtledoves or two young pigeons, he may bring two quarts of fine flour as an offering for his sin. He must not put olive oil or frankincense on it, for it is a sin offering.

12He is to bring it to the priest, who will take a handful from it as its memorial portion and burn it on the altar along with the food offerings to the Lord; it is a sin offering.

13In this way the priest will make atonement on his behalf concerning the sin he has committed in any of these cases, and he will be forgiven. The rest will belong to the priest, like the grain offering.”
