Ishodad of Merv

Eliphaz employs "murmur" and "voice" as words to express his ideas about God. As … the murmur and the voice strike our ears, they have no form or aspect. We only receive their sensation. Just as it is not possible to see a "murmur" or "voice," so we must realize the same is true of our thoughts about the divine nature. We receive our perception and knowledge of the divine nature as God gives us these thoughts, but this is not something that we can perceive through forms.
