EXOD901 It has already been stated that the relation of nature to the Torah is like that of a servant to his master; for the forces of nature, in governing the world, operate in accordance with the Torah, as it says: “You will serve Hashem your God, and He will bless your bread and your water; and I will remove sickness from your midst” (Shemos 23:25 ); “He said, ‘If you listen carefully to Hashem your God and do that which is right in His eyes, obeying His commandments and keeping all His statutes, then I will not bring upon you all the sickness which I brought upon Egypt, for I am God your cap Healer’” (ibid. 15:26). There are many similar passages.
