Leviticus 4:23-25

²³then his sin which he has committed is made known to him, he must bring for his sacrifice a goat, a male without blemish.

²⁴He will lay his hand on the head of the goat and kill it in the place where they kill the burnt offering before Yahweh. This is a sin offering.

²⁵The priest will take the blood of the sin offering with his finger and put it on the horns of the altar for burnt offerings, and he will pour out its blood at the base of the altar of burnt offering.
