Leviticus 5:12

He shall sprinkle some of the blood of the sin offering on the side of the altar; and the rest of the blood shall be drained out at the base of the altar. It is a sin offering.

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.

“‘But if he can’t afford two turtledoves or two young pigeons, then he shall bring as his offering for that in which he has sinned, one tenth of an ephah of fine flour for a sin offering. He shall put no oil on it, and he shall not put any frankincense on it, for it is a sin offering.

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.’”

The LORD spoke to Moses, saying,

“If anyone commits a trespass, and sins unwittingly regarding the LORD’s holy things, then he shall bring his trespass offering to the LORD: a ram without defect from the flock, according to your estimation in silver by shekels, according to the shekel of the sanctuary, for a trespass offering.
