A second century BC historian can't remember his, wrote that the God of the Jews was Helios. Archeology shows that many things in the Bible were just plain made up stories or legends
It has also been shown that the original god of the Israelites was the Canaanite God El then it changed to Baal Hadad with all the atributes of El being added to Baal including his wives Asherah and Anat. So again by the time you get to the New Testament it's anyone's guess who or what the yhwh represents.
