Deuteronomy 24:8

Leprosy. Do nothing which may expose you to the danger of being infected, and if you have the misfortune to contract it, obey the directions of the priests. (Calmet) --- It seems from this and the following verse that God frequently punished disobedience to his ministers, as he did Mary [Miriam], (Numbers xii.,) by inflicting upon them this shameful disorder. (Haydock) --- So he punished king Ozias, 2 Paralipomenon xxvi. (Menochius) --- The design of this precept is, therefore, not so much to order people not to contract a disease, which they cannot perhaps always avoid, as to caution them against pride and rebellion. (Haydock)
