Speak unto the children of Israel
 From whence we learn, says the above mentioned writer, that these uncleannesses were only usual among the children of Israel, not among the Gentiles; that is, the laws respecting them were only binding on the one, and not on the other F19: 
 and say unto them, when any man;
 in the Hebrew text it is, "a man, a man", which the Targum of Jonathan paraphrases, a young man, and an old man: 
 hath a running issue out of his flesh;
 what physicians call a "gonorrhoea", and we, as in the margin of our Bibles, "the running of the reins": 
 [because of] his issue, he [is] unclean;
 in a ceremonial sense, though it arises from a natural cause; but if not from any criminal one, from a debauch, but from a strain, or some such like thing, the man was not defiled, otherwise he was; the Targum of Jonathan is, 
``if he sees it three times he is unclean;''so the Misnah F20.
