Leviticus 1:14-17
14 “If his gift to the Lord is a burnt offering of birds,(A) he is to present his offering from the turtledoves(B) or young pigeons.(a)(C)
15 Then the priest must bring it to the altar, and must twist off its head and burn it on the altar; its blood should be drained at the side of the altar.
16 He will remove its digestive tract,(b) cutting off the tail feathers, and throw it on the east side of the altar at the place for ashes.(D)
17 He will tear it open by its wings without dividing the bird.(E) Then the priest is to burn it on the altar on top of the burning wood. It is a burnt offering, a fire offering of a pleasing aroma to the Lord.
