EXOD803 The demand of Jewish sources that one act to protect others [e.g. Leviticus 19:16] is not only concerned with the prevention of bodily harm. The Sefer Hachinukh, the thirteenth-century Spanish study of the reasons behind the mitzvot, explains the biblical commandment in Exodus “and if you see the donkey of your enemy straining under its burden,... you shall surely help him.” [this verse]. (As to the scriptures saying a donkey, it does not mean a donkey specifically, but any beast. It is only that scripture spoke of what is the usual purpose of a donkey-- for carrying burdens.) “It is a religious duty to help unload a man laden with a burden as well. Furthermore, even if he suffers only the loss of his goods and possessions, it is a religious obligation for us to take pity on him. At the root of this precept lies the purpose: to teach our spirit the quality of compassion, which is a noble trait of character. [A fortiori] there is no need to say that a duty lies on us to take pity on a man who is suffering physical pain.” Parshat Mishpatim, Mitzvah 80.
