There is no longer any doubt the Hebrew word “Adon” (Lord) is from the ancient Egyptian “Aten” or “Aton” as it is spelled by some scholars. The name “Aten” also closely resmbles the Hebrew word “Adonai” which means “my Lord” - the root being “Adon.”
Many have pointed out the numerous similarities between the Hebrew or Aramaic hymn Psalm 104 and the Great Hymn to Aten composed by Akhenaten. Psalm 104 is attributed to the great Prophet Moses, who has also been identified as none other than Akhenaten (Akhnaten) himself.
While the sun is used as a symbol to represent God in many cultures, Aten is neither the sun nor is He the “sun god” as some have erroneously suggested.
The Scriptures use the symbol of the sun as representing God. Notice how the Psalmist describes the attributes of God:
“Who coverest thyself with light as with a garment; Who stretchest out the heavens like a curtain. Who layeth the beams of his chambers in the waters. Who maketh the clouds his chariot; Who walketh on the wings of the wind; Who maketh winds his messengers; flames of fire his ministers (Psalm 104:2,3)
It should be noted that the sun itself was not worshipped by the faithful monotheistic Egyptians or Hebrews, but it was served as a ruling deity by the polytheists among other ancient Egyptians.
