According to the bible, until the time of abraham, yahweh didn't make his name known to his devotees. That means noah, abel and others supposedly faithful, were worshipping a god whose name they knew not. Noah even built his boat for his unknown god.
Later, many different names were put on the jewish diety. Yahweh of armies, yahweh nissi, baal, lord. In writing genesis, moses, the claimed author used the term elohim. Elo = goddess, him = masculine plural, in other words, 'the gods', generally. Towards the middle of the ot, the use of yahweh became quite popular. Strangely, the later ot books again started to avoid divine name usage (yes, because of fear of him). Even more strangely, the divine appellation is totally gone from the nt. The standard christian reason given is because yahweh incarnated as jesus. If this were true, then why was not jesus called yahweh since when he was born? At any rate, jesus christ would then be added to the list of vocolisations by which jews called their god.
