Leviticus 7:2

In the place where they kill the burnt offering they shall kill the guilt offering , and its blood shall be thrown against the sides of the altar .

The guilt offering is to be slaughtered in the place where the burnt offering is slaughtered, and its blood is to be splashed against the sides of the altar.

In the place where they kill the burnt offering shall they kill the trespass offering : and the blood thereof shall he sprinkle round about upon the altar.
