Leviticus 1:15

¹³And they shall wash the entrails and the feet with water, and the priest shall bring all the parts and put them on the altar: it is a burnt offering, a sacrifice, a smell of sweet savor to the Lord.

¹⁴And if he bring his gift, a burnt offering to the Lord, of birds, then shall he bring his gift of doves or pigeons.

— Leviticus 1:15 —

¹⁶And he shall take away the crop with the feathers, and shall cast it forth by the altar toward the east to the place of the ashes.

¹⁷And he shall break it off from the wings and shall not separate it, and the priest shall put it on the altar on the wood which is on the fire: it is a burnt offering, a sacrifice, a sweet-smelling savor to the Lord.
