Leviticus

Only be sure that thou eat not the blood: for the blood is the life; and thou mayest not eat the life with the flesh.

Also before they burnt the fat, the priest’s servant came, and said to the man that sacrificed, Give flesh to roast for the priest; for he will not have sodden flesh of thee, but raw.

And if any man said unto him, Let them not fail to burn the fat presently, and then take as much as thy soul desireth; then he would answer him, Nay; but thou shalt give it me now: and if not, I will take it by force.

Speak unto the children of Israel, saying, Ye shall eat no manner of fat, of ox, or of sheep, or of goat.

For whosoever eateth the fat of the beast, of which men offer an offering made by fire unto the Lord, even the soul that eateth it shall be cut off from his people.
