Leviticus 3:1, 16-17

And if his oblation be a sacrifice of peace-offerings; if he offer of the herd, whether male or female, he shall offer it without blemish before Jehovah.

And the priest shall burn them upon the altar: it is the food of the offering made by fire, for a sweet savor; all the fat is Jehovah’s. It shall be a perpetual statute throughout your generations in all your dwellings, that ye shall eat neither fat nor blood.
