Exodus 29:22 - Clarke's commentary and critical notes on the Bible

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: The fat and the rump - The rump or tail of some of the eastern sheep is the best part of the animal, and is counted a great delicacy. They are also very large, some of them weighing from twelve to forty pounds' weight; "so that the owners," says Mr. Ludolf, in his History of Ethiopia, "are obliged to tie a little cart behind them, whereon they put the tail of the sheep, as well for the convenience of carriage, and to ease the poor creature, as to preserve the wool from dirt, and the tail from being torn among the bushes and stones." An engraving of this kind of sheep, his tall, cart, etc., may be seen at p. 53 of the above work.
