Vayikra 7:3-5

Orthodox Jewish Bible

³ And he shall offer of it all the chelev thereof; the tail, and the chelev that covereth the innards,

⁴ And the two kidneys, and the chelev that is on them, which is on the flanks, and the diaphragm that is above the liver, with the kidneys, it shall he remove;

⁵ And the kohen shall burn them upon the Mizbe’ach for an offering made by eish unto Hashem; it is an asham (trespass offering).
