Leviticus 24:22

22.Ye shall have one manner of law. That the people of Israel, with their usual arrogance, might not suppose the race of Abraham only to be privileged, the Law is extended also to foreigners; and thus God shows that the whole body of the human race are under His care, so that He would not have those that are farthest off exposed to the licentious violence of the ungodly. In other points tie provided special privileges for His elect people; but here, because He created all men without exception after His own image, He takes them under His care and protection, so that none might injure them with impunity.
