Parshat Ki Tetze
by Rabbi Avi Billet
The Torah speaks of the military encampment, and a level of purity, holiness, and even cleanliness which is meant to be maintained while out in the field. One aspect, the covering of human waste, can verily be understood to be the Torah’s way of also protecting from filth and disease which can easily be spread in a military space, when people do not properly tend to hygiene. [Incidentally, until the 20th century, in just about every military conflict in history, more soldiers died from disease, starvation and the elements than from combat. Even some fronts in WWI and WWII are disputed about these outcomes, but after the World Wars, this has certainly been the case – now, in general, there are far more casualties from combat than from those other factors.]
