Exodus 29:22  (King James Version)
Also thou shalt take of the ram the fat and the rump, and the fat that covereth the inwards, and the caul above the liver, and the two kidneys, and the fat that is upon them, and the right shoulder; for it is a ram of consecration:

Also thou

the rump
{Alyah} is the large tail of a species of eastern sheep.
"This tail," says Dr. Russell, "is very broad and large, terminating in a small appendix that turns back upon it. It is of a substance between fat and marrow, and is not eaten separately, but mixed with lean meat in many of their dishes, and also often used instead of butter. A common sheep of this sort, without the head, feet, skin, and entrails, weighs about twelve or fourteen {Aleppo rotoloes,} (a {rotoloe} is five pounds,) of which the tail is usually three {rotoloes} or upwards; but such as are of the largest breed, and have been fattened, will sometimes weigh about thirty {rotoloes,} and the tails of these ten."
