Leviticus 1:13-15

New Catholic Bible

¹³ He shall wash the entrails and the legs with water, and then the priest shall burn all of it on the altar as a burnt offering, a pleasing fragrance to the Lord.

¹⁴ “If the burnt offering to the Lord consists of birds,^[a] then let him bring his offering of turtledoves or young pigeons. 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.
