Exegetical note: God's revelation of the divine name, YHWH (or JHWH or JeHoWaH) to Moses is almost a tease. The basis of the name is "to be," but is so ambiguous in form that it may mean "I am who I am," "I wili be what I will be," or "He causes to be." The first two of these suggest a more Greek, philosophical, abstract "Being," an appropriate object of speculation. The third seems more Hebraic, for it bespeaks activity and action, which is exactly what God promises (and delivers!) on behalf of the captive Israelites.
