Leviticus 1:12-14

12 ‘And he shall cut it into its pieces, with its head and its fat, and the priest shall arrange them on the wood which is on the fire on the slaughter-place.

13 ‘But the entrails and the legs he washes with water. And the priest shall bring it all and burn it on the slaughter-place. It is an ascending offering, an offering made by fire, a sweet fragrance to יהוה.

14 ‘And if the ascending offering of his offering to יהוה is of birds, then he shall bring his offering of turtledoves or young pigeons.
