Leviticus 15:11 - Clarke's commentary and critical notes on the Bible

And whomsoever he toucheth that hath the issue, and hath not rinsed his hands in water, he shall wash his clothes, and bathe himself in water, and be unclean until the even. And whomsoever he toucheth - Here we find that the saliva, sitting on the same seat, lying on the same bed, riding on the same saddle, or simple contact, was sufficient to render the person unclean, meaning, possibly, in certain cases, to communicate the disorder; and it is well known that in all these ways the contagion of this disorder may be communicated. Is it not even possible that the effluvia from the body of an infected person may be the means of communicating the disease? Sydenham expressly says that it may be communicated by lactation, handling, the saliva, sweat, and by the breath itself, as well as by those grosser means of which there is no question. But the term unclean, in this and the following cases, is generally understood in a mere legal sense, the rendering a person unfit for sacred ordinances. And as there was a mild kind of gonorrhea that was brought on by excessive fatigue and the like, it may be that kind only which the law has in view in the above ordinances.
