Leviticus 7:2-4

Complete Jewish Bible

² They are to slaughter the guilt offering in the place where they slaughter the burnt offering, and its blood is to be splashed against all sides of the altar. ³ He is to offer all its fat — the fat tail, the fat covering the inner organs, ⁴ the two kidneys, the fat on them near the flanks, and the covering of the liver, which he will remove with the kidneys.
