Leviticus 7:25-30

²⁵Whoever eats the fat of an animal that men can offer as a sacrifice by fire to Yahweh, that person must be cut off from his people.

²⁶You must eat no blood whatsoever in any of your houses, whether it is from a bird or an animal.

²⁷Whoever eats any blood, that person must be cut off from his people.'”

²⁸So Yahweh spoke to Moses and said,

²⁹“Speak to the people of Israel and say, 'He who offers the sacrifice of a peace offering to Yahweh must bring part of his sacrifice to Yahweh.

³⁰The offering for Yahweh to be made by fire, his own hands must bring it. He must bring the fat with the breast, so that the breast may be waved as a wave offering before Yahweh.
