TSK · Leviticus 3:16

You are to take all the fat that covers the entrails, and the lobe that is above the liver, and the two kidneys and the fat that is on them, and burn them on the altar.

Then the one presenting the offering must present a gift to the LORD from the peace offering sacrifice: He must remove the fat that covers the entrails and all the fat that surrounds the entrails,

Then he must present from it his offering as a gift to the LORD: the fat which covers the entrails and all the fat on the entrails,

Then the priest must offer all of its fat up in smoke on the altar like the fat of the peace offering sacrifice. So the priest will make atonement on his behalf for his sin and he will be forgiven.

“Tell the Israelites,‘You must not eat any fat of an ox, sheep, or goat.

Then fire went out from the presence of the LORD and consumed the burnt offering and the fat parts on the altar, and all the people saw it, so they shouted loudly and fell down with their faces to the ground.

Also, before they burned the fat the priest’s attendant would come and say to the person who was making the sacrifice,“Give some meat for the priest to roast! He won’t accept boiled meat from you, but only raw.”

There was a large number of burnt sacrifices, as well as fat from the peace offerings and drink offerings that accompanied the burnt sacrifices. So the service of the LORD’s temple was reinstituted.

The Levitical Priests“‘But the Levitical priests, the descendants of Zadok who kept the charge of my sanctuary when the people of Israel went astray from me, will approach me to minister to me; they will stand before me to offer me the fat and the blood, declares the Sovereign LORD.
