Exodus 29:17

Thou shalt cut the ram in pieces. — This was the ordinary practice, not only among the Hebrews, but also among other nations, as the Egyptians (Herod. ii. 40), the Greeks, the Romans, and others. It was probably found to facilitate the burning of the animal, which was with difficulty consumed entire. The shoulder, thigh, head, ribs, rump, heart, and kidneys appear separate in the representations of sacrifices on Egyptian altars.
