“You may not ignore it” (v3). The laws for life in ancient Israel went beyond punishment for crimes; they also instructed people to look out for one another’s interests. In the communal, family-centered world, individuals were instructed to take care of wandering livestock and make sure they were returned to their owners (v1-4). No one was permitted to “ignore” the potential harm to someone else. The law also tried to impose some sort of rough criteria for dealing with adultery and accusations of rape.
“That it may go well with you” (v22). It will only go well with us individually if we also seek the welfare of those around us.
