Leviticus 1:15-17

New Catholic Bible

¹⁵ The priest shall bring them to the altar and wring off their heads. He shall burn them upon the altar, but their blood is to be drained out on the side of the altar. ¹⁶ He shall tear out their crops with their feathers and toss them to the east side of the altar, the place where the ashes are kept. ¹⁷ He shall split the birds into two halves holding on to their wings, but he shall not separate the pieces. Then the priest shall burn them on the burning wood upon the altar. It is a burnt offering, a pleasing fragrance to the Lord.
