SEV Biblia, Chapter 13:31
Mas cuando el sacerdote hubiere mirado la llaga de la tiña, y no pareciere estar más profunda que la tez, ni fuere en ella pelo negro, el sacerdote encerrará al llagado de la tiña por siete días;
John Gill's Bible Commentary
Ver. 31. And if the priest look on the plague of the scall , etc.] As it may appear in another person, brought to him for inspection and examination: and, behold, it [be] not in the sight deeper than the skin ; it do not seem to be got into the flesh, or lower than the skin: and [that there is] no black hair in it ; or, “but no black hair in it”; for, as Jarchi says, if there was a black hair in it, he would be clean, and there would be no need of shutting up; for black hair in scalls is a sign of cleanness, as it is said, ( Leviticus 13:37); it would be a clear case that such a man had no leprosy on him; for black hair is a token of a strong and healthful constitution; and there could remain no doubt about it, and it would require no further trial and examination: Ben Gersom says it means two black hairs; and further observes, that black hair in the midst of a scall is a sign of cleanness; but this being wanting, then the priest shall shut up [him that hath] the plague of the scall seven days ; from the time of his viewing the scall; and so Ben Gersom, this is the seventh day from the time of looking upon the scall.
Matthew Henry Commentary
Verses 18-44 - The priest is told what judgment to make, if there were any appearanc of a leprosy in old sores; and such is the danger of those who havin escaped the pollutions of the world are again entangled therein. Or, in a burn by accident, ver. #(24). The burning of strife and contentio often occasions the rising and breaking out of that corruption, whic proves that men are unclean. Human life lies exposed to man grievances. With what troops of diseases are we beset on every side and thy all entered by sin! If the constitution be healthy, and the body lively and easy, we are bound to glorify God with our bodies Particular note was taken of the leprosy, if in the head. If the leprosy of sin has seized the head; if the judgment be corrupted, an wicked principles, which support wicked practices, are embraced, it is utter uncleanness, from which few are cleansed. Soundness in the fait keeps leprosy from the head.
