Leviticus 4:27

24 And he shall lay his hand upon the head of the goat, and kill it in the place where they kill the burnt-offering before the LORD: it [is] a sin-offering.

25 And the priest shall take of the blood of the sin-offering with his finger, and put [it] upon the horns of the altar of burnt-offering, and shall pour out his blood at the bottom of the altar of burnt-offering.

26 And he shall burn all his fat upon the altar, as the fat of the sacrifice of peace-offerings: and the priest shall make an atonement for him as concerning his sin, and it shall be forgiven him.

27 And if any one of the common people shall sin through ignorance, while he doeth [somewhat against] any of the commandments of the LORD [concerning things] which ought not to be done, and be guilty;

28 Or if his sin which he hath sinned shall come to his knowledge: then he shall bring his offering, a kid of the goats, a female without blemish, for his sin which he hath sinned.

29 And he shall lay his hand upon the head of the sin-offering, and slay the sin-offering in the place of the burnt-offering.

30 And the priest shall take of the blood of it with his finger, and put [it] upon the horns of the altar of burnt-offering, and shall pour out all the blood thereof at the bottom of the altar.
