Leviticus 4:23-25

²³if his sin, wherein he hath sinned, be known to him, he shall bring for his offering a goat, a male without blemish.

²⁴And 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.

²⁵And 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 the remaining blood thereof shall he pour out at the base of the altar of burnt-offering.
