Leviticus 1:14-17

¹⁴If his offering to Yahweh is a burnt offering of birds, then he shall offer his offering of turtle-doves, or of young pigeons. ¹⁵The priest shall bring it to the altar, and wring off its head, and burn it on the altar; and its blood shall be drained out on the side of the altar; ¹⁶and he shall take away its crop with its filth, and cast it beside the altar on the east part, in the place of the ashes: ¹⁷and he shall tear it by its wings, but shall not divide it apart. The priest shall burn it on the altar, on the wood that is on the fire. It is a burnt offering, an offering made by fire, of a sweet savor to Yahweh.
