Leviticus 5:13

10 He shall offer the second for a burnt offering, according to the ordinance; and the priest shall make atonement for him concerning his sin which he has sinned, and he shall be forgiven.

11 "'But if he can't afford two turtledoves, or two young pigeons, then he shall bring his offering for that in which he has sinned, the tenth part of an ephah of fine flour for a sin offering. He shall put no oil on it, neither shall he put any frankincense on it, for it is a sin offering.

12 He shall bring it to the priest, and the priest shall take his handful of it as the memorial portion, and burn it on the altar, on the offerings of the Lord made by fire. It is a sin offering.

13 The priest shall make atonement for him concerning his sin that he has sinned in any of these things, and he will be forgiven; and the rest shall be the priest's, as the meal offering.'"

14 The Lord spoke to Moses, saying,

15 "If anyone commits a trespass, and sins unwittingly, in the holy things of the Lord; then he shall bring his trespass offering to the Lord, a ram without blemish from the flock, according to your estimation in silver by shekels, after the shekel of the sanctuary, for a trespass offering.

16 He shall make restitution for that which he has done wrong in the holy thing, and shall add a fifth part to it, and give it to the priest; and the priest shall make atonement for him with the ram of the trespass offering, and he will be forgiven.
