Exodus 22:22

Ye shall not afflict any widow, or fatherless child - It is remarkable that offenses against this law are not left to the discretion of the judges to be punished; God reserves the punishment to himself, and by this he strongly shows his abhorrence of the crime. It is no common crime, and shall not be punished in a common way; the wrath of God shall wax hot against him who in any wise afflicts or wrongs a widow or a fatherless child: and we may rest assured that he who helps either does a service highly acceptable in the sight of God.
