In Islam It has been stated that "cleanliness is half of the religion".. While it may metaphorically means both physical and spritual but Physical tidiness is more highlightened.. I guess there you have the First ethical rule in importance defined by Allah..
Jahve( in jewish I am the one that is), God-The creator of the universe. God-the spirit of existing and creation. In india there are three "gods" the one who created this world , one who insures existance, one who destroys it. The first rule of ethics is to exist.
