LEV482 It is a negative commandment not to refrain from rescuing one's fellow-man from danger for Scripture says, neither shall you stand idly by the blood of your brother [this verse]. For example, if someone sees another person drowning in the river, or in any other perils, he is duty-bound to save him in any way possible. Included in this is the duty to save one's fellow-man from a monetary loss: for example, if he knows that a heathen or a bandit wishes to attack his fellow, and it lies in his ability to pacify him [the outlaw], he has a duty to pacify him.
