New Catholic Bible

¹⁵ its two kidneys with their fat, the fat around the loins, and the lobe of the liver that he will detach along with the kidneys. ¹⁶ Then the priest shall burn them on the altar as food offered to the Lord by fire. All fat belongs to the Lord.

¹⁷ “It will be a perpetual statute throughout all your generations in all of your dwellings: you must not eat fat or blood.”
