LEV504 Jewish moralists have been quick to point out, in considering our ongoing obligation to rescue the lives and property of others when they are in danger [this verse], that we must train ourselves to make quick and effective responses to new situations and must develop ability to make a realistic judgment as to what is possible. Rabbi Jonah Gerondi makes this important practical suggestion: "It is good and very proper that there be in every community volunteers consisting of intelligent people who should be prepared and equipped for all means of rescue work [hatzalah] in the event that any man or woman be in trouble. For behold, we are obligated to bestir ourselves for the lost ox or sheep of our neighbor and mind it until the owner claims it, how much more should we be prepared to work for the well-being of their owners themselves. As the prophet Isaiah says: "… Bring the poor that are cast out to the house" (Gerondi, Sha'arei Teshuvah, p. 68. Isaiah 58:7).
