Leviticus 4:28-30

28if his sin, which he hath sinned, be made known to him, then he shall bring for his oblation a goat, a female without blemish, for his sin which he hath sinned.

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

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