This term refers to the outer surface of the human body—the skin or flesh as a physical covering. In Acts 19:12, handkerchiefs and aprons that had touched Paul's skin were taken to the sick, and diseases left them. The multilingual evidence (English 'skin', Spanish 'cuerpo', French 'peau') confirms this physical, tactile sense of bodily surface contact, emphasizing the concrete, material nature of the healing objects.
