LEV368 It is a negative commandment not to take anything in robbery from one's fellow-man by main force as Scripture says, nor shall you rob him [this verse]. The prohibition of this injunction is on anything worth from a p'rutah [the smallest coin] and up; yet even less than that is forbidden [although not punishable], like any half of [less than] a minimum amount. If a person takes [even] something worth a p'rutah in robbery from his fellow-man, it is as though he takes his life.
