The Torah records the total number of adult males in each tribe. Miraculously, all those counted were fit to go to war; they were all strong, all able-bodied men.
Health and Healing
וַיִּהְיוּ בְנֵי רְאוּבֵן . . . כֹּל יֹצֵא צָבָא: (במדבר א:כ)
[The tally] of the tribe of Reuben . . . all who were fit to serve in the army. Numbers 1:20

All the sick and crippled Jews were healed when the Torah was given; thanks to the protective Clouds of Glory, the Jews remained healthy throughout their journey, despite the adverse conditions of the desert.

We see from this that the Jewish people – by virtue of their connection to G‑d expressed through studying the Torah and fulfilling its commandments – were not bound by the laws of nature. Furthermore, their ability to override nature was self-evident, expressed not only in spiritual concerns, but in physical health and well-being as well.

This holds true today as it did when the Torah was given on Mount Sinai. To the extent that we live our lives according to the dictates of the Torah, we too will be blessed with spiritual and physical health, despite any obstacles posed by the laws of nature.1
