An examination of the Hebrew Scriptures reveals the ethical situations in ancient Israel as a structural analysis, and exposes a covenantal triangle that features a dynamic of giving and receiving, taking and paying penalties, as a meme for human relationships. This can be applied to groups as well as individuals and is surprisingly applicable to life in the twenty-first century. Two senses of "e;Law"e;--natural scientific discoveries and the rules laid down by a divine creator--lead to frames for considering these covenantal relationships, and even the existence of "e;Sin."e; Are we bound to obey the rules laid down by God, or may we decide what is best for us?
