I would recommend that you check out what I have written regarding the reasons and circumstances requiring two, four and five times restitution at http://www.missiontoisrael.org/8thcom-pt1.php.
There?s something here that I don?t think most theonomists have considered. It can be found in my booklet Thou shalt not steal. Scroll down to the heading ?Eighth Commandment Statutes.?
