The passage from Deuteronomy 8 gives us the key. The primary reference of “word that comes out of God’s mouth” was the “manna” that the Israelites lived on during their years of wandering in the desert between Canaan and Egypt. Now manna is an interesting term. It basically means “whatever it is,” or “what is it?” Manna was a form of physical substance that was unknown. It was, in fact, a digestible form of matter suited to the physical needs of human beings and produced directly by God’s action, or “word,” not by a process already in place in nature.
