Leviticus 3:14-17

14And from his offering he shall present a food offering to the LORD: the fat that covers the entrails, all the fat that is on them, 15both kidneys with the fat on them near the loins, and the lobe of the liver, which he is to remove with the kidneys. 16Then the priest is to burn the food on the altar as a food offering, a pleasing aroma. All the fat is the LORD’s.

17This is a permanent statute for the generations to come, wherever you live: You must not eat any fat or any blood.”
