Leviticus 7:25-30

²⁵For anyone who takes as food the fat of any beast of which men make an offering by fire to the Lord, will be cut off from his people.

²⁶And you are not to take for food any blood, of bird or of beast, in any of your houses.

²⁷Whoever takes any blood for food will be cut off from his people.

²⁸And the Lord said to Moses,

²⁹Say to the children of Israel: He who makes a peace-offering to the Lord, is to give an offering to the Lord out of his peace-offering:

³⁰He himself is to take to the Lord the offering made by fire, even the fat with the breast, so that the breast may be waved for a wave offering before the Lord.
