Exodus 29:13-15

New Catholic Bible

¹³ “Take the fat that surrounds its entrails, the lobe of the liver, the two kidneys and the fat that surrounds them, and burn them as a sacrifice on the altar. ¹⁴ But the meat of the bull, its skin and its dung, you must burn outside the camp. It is a sin offering.

¹⁵ “Then take one of the rams. Aaron and his sons shall lay their hands on its head.
