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 "Law"--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 "Sin." Are we bound to obey the rules laid down by God, or may we decide what is best for us?
