muscles

And I looked, while the sheep were eaten up by the dogs, by the eagles, and by the kites. They neither left them their body, nor their skin, nor their muscles, until their bones alone remained; until their bones fell upon the ground. And the sheep became diminished.

For God made all things good in their order, the five senses in the head, and He joined on the neck to the head, adding to it the hair also for comeliness and glory, then the heart for understanding, the belly for excrement, and the stomach for grinding, the windpipe for taking in the breath, the liver for wrath, the gall for bitterness, the spleen for laughter, the reins for prudence, the muscles of the loins for power, the lungs for drawing in, the loins for strength, and so forth.
