Leviticus 7:24-33

²⁴You can use the fat of an animal found dead or killed by wild beasts for whatever purpose you want, but you must not eat it.

²⁵Anyone who eats the fat of an animal from a food offering presented to the Lord must be expelled from their people.

²⁶You must not eat the blood of any bird or animal in any of your homes.

²⁷Anyone who eats blood must be expelled from their people.’”

²⁸The Lord told Moses,

²⁹“Give these instructions to the Israelites. Tell them that if you present a peace offering to the Lord you must bring part of it as a special gift to the Lord.

³⁰You must personally bring the food offerings to the Lord; bring the fat as well as the breast, and wave the breast as a wave offering before the Lord.

³¹The priest shall burn the fat on the altar, but the breast is for Aaron and his sons.

³²Give the right thigh to the priest as a contribution from your peace offering.

³³The priest as a descendant of Aaron who offers the blood and fat of the peace offering has the right thigh as his share.
