Isaiah 6 New King James Version (NKJV)
6 In the year that King Uzziah died, I saw the Lord sitting on a throne, high and lifted up, and the train of His robe filled the temple. 2 Above it stood seraphim; each one had six wings: with two he covered his face, with two he covered his feet, and with two he flew.
The common perception of the Seraphim is the concept of the European looking Angels, but the earliest usage of the term was ascribe to demons. In Sumerian mythology Demons are not necessarily evil since they work closely with humans and gods to hold at bay the forces of chaos. The word Seraphim comes from the plural of the Hebrew word “Saraph”, which means “to burn.” Could it be referring to the burning rocket engines of the god’s flying crafts? Since the earliest Sumerians must have seen their rulers in the skies represented their gods as “flying serpents” in their early writings. In Isaiah 6:1ff, the Seraphim is described as creatures with six wings and does not retain their serpentine form. They are described as if they now take the form of humans, with faces, hands and feet. It is also interesting to note that Lucifer being the “snake” in Eden has Angelic connections. In the Aztek culture, Quetzalcoatl is depicted as a flying reptile – the Feathered Serpent.
