Lev Leviticus, chapter Book of Leviticus, chapter 3
And the two kidneys, and the fat that [is] upon them, which [is] by the flanks, and the caul (membrane; fatty tissue around a bodily organ) above the liver, with the kidneys, it shall he take away.
And the priest shall burn them upon the altar: [it is] the food of the offering made by fire for a soothing aroma: all the fat [is] the LORD-Yehōvah’s [Messiah Pre-Incarnate].Exo 29:13
