Leviticus 7:25-30

²⁵Anyone who eats the fat of an animal from which an offering has been made to Yahweh must no longer be allowed to associate with God's people.

²⁶And wherever you live, you must not eat the blood of any bird or animal.

²⁷If anyone eats blood, he must no longer be allowed to associate with God's people.”

²⁸Yahweh also said to Moses/me,

²⁹“Tell the Israeli people this: Anyone who brings an offering to maintain fellowship with Yahweh must bring part of it to be a sacrifice to Yahweh.

³⁰He himself must bring the offering that will be burned in the fire. He must bring the fat along with the breast of the animal and lift it up in front of Yahweh to indicate that it is an offering to him.
