Leviticus 3:1, 16-17

‘When his offering is a sacrifice of a peace offering, if he offers it of the herd, whether male or female, he shall offer it without blemish before the LORD.

and the priest shall burn them on the altar as food, an offering made by fire for a sweet aroma; all the fat is the LORD’s. ‘This shall be a perpetual statute throughout your generations in all your dwellings: you shall eat neither fat nor blood.’ ”
