Leviticus 3:13

10 And the two kidneys, with the fat on them, which is by the top part of the legs, and the fat joining the liver and the kidneys, he is to take away;

11 That it may be burned by the priest on the altar; it is the food of the offering made by fire to the Lord.

12 And if his offering is a goat, then let it be placed before the Lord,

13 And let him put his hand on the head of it and put it to death before the Tent of meeting; and the sons of Aaron are to put some of its blood on and round the altar.

14 And of it let him make his offering, an offering made by fire to the Lord; the fat covering the inside parts and all the fat on the inside parts,

15 And the two kidneys, with the fat on them, which is by the top part of the legs, and the fat joining the liver and the kidneys, let him take away;

16 That it may be burned by the priest on the altar; it is the food of the offering made by fire for a sweet smell: all the fat is the Lord's.
