Commentary for Job 1:14

beside them Heb. על ידיהם lit. on their hands. This is an expression of a place only because it is prepared and available at his hand. Our Sages of blessed memory said in the Aggadah (Baba Bathra 15b, 16a), that the Holy One, blessed be He, gave them a taste of the world to come; for after the plowing by the she-donkeys, they would sow with the plowing, and the she-donkeys would immediately graze on the young greens from the furrow.

Maimonides has also categorized the types of harm that can befall man: The evils that befall man are of three kinds:

The first kind of evil is that which befalls a man because he is subject to genesis and destruction or because he possesses a body...in consequence of changes in the elements e.g. through bad air or thunderstorms or land-slips.
