... This God Yahweh, or Jehovah, as we have incorrectly transliterated it, seems to have been a God closely connected with the volcanic mountain near which Moses kept the sheep of his father-in-law Jethro.  He manifested himself in thunder and lightning and storm, a "God of battles," who fought for his people and led them on to victory.  True, this is not the conception we get of Jehovah in the prophets and the psalmists of a later age, but it is necessary to remember that it was by gradual stages and only after a long development that the idea of God became what we see it to be in Jeremiah and Isaiah.  Yahweh was to these early tribesmen the divine Being who had his residence in the sacred mountain and who was willing to become their special protector—they had not risen to the sublime of the monotheism of a later day...
