Leviticus 7:23-25

Thomson(i) 23 Speak to the children of Israel, and say, You shall not eat any suet of cattle, nor of sheep, nor of goats. 24 The suet of beasts which die of themselves, or which are torn by wild beasts, may be used for any kind of work; but shall not be eaten for food. 25 Whoever eateth of the suet of cattle of which he is to make an offering of homage to the Lord, that person shall be cut off from among his people.
