Leviticus 5
8 Ref And let him take them to the priest, who will first give the sin-offering, twisting off its head from its neck, but not cutting it in two;
9 Ref And he is to put drops of the blood of the offering on the side of the altar, and the rest of the blood is to be drained out at the base of the altar; it is a sin-offering.
10 Ref And the second is for a burned offering, in agreement with the law; and the priest will take away his sin and he will have forgiveness.
