The word Logos was first used in such form by Heraclitus in the 6th century BC (one of my favourite philosophers). It is said to correspond perfectly to the Zoroastrian term Asha, which is most likely from where Heraclitus learned a great deal. Greek philosophy, especially Platonism, was influenced by Zoroastrianism. Judaism was too. Some Psalms are almost Gathic in content, indicating they were composed during the exile in Mesopotamia.
There is a lot of Persian influence in Judaism. Also, I have read that Druze has much Avestan influence.
Logos may correspond to Asha but that does not appear to be the etymology. What is the etymology of logos? The etymology is how the cultural symbology can be determined.
