BTW, YHWH was one deity in the southern part of the Arabian Peninsula that became adopted by some Jewish traders there and brought north into eretz Israel according to some researchers posted in BAR a few months ago. Obviously, it eventually became believed to be the monotheistic name for God.
That is not news to those of us who study the Scriptures.
1) When the descendants of Noah's sons were scattered throughout the earth, they already knew the name of Jehovah (Gen. 10:32).
2) Abraham, called by God to leave the country where he lived, had several children who lived on their own side. Ishmael, who was his first child with an Egyptian slave, went to Arab land and was patriarch of many tribes (Gen. 25: 13-16).
3) Melchizedek was a king who lived in Salem, the city that was located in what would eventually become Jerusalem. This king was a priest of the Most High, and it is very likely that he knew him by his name Jehovah (Gen. 14.18).
4) Lot, Abraham's nephew, was the ancestor of the Moabites and Ammonites, who had lands adjoining Canaan, before Israel possessed neighboring lands (Gen. 19:36-38).
5) Abraham had more sons with other women after Sarah died, and he gave them a separate inheritance from Isaac, and they left and started families in other surrounding places. (Gen. 25: 1-6) When Moses fled from Egypt, he went to Midian, the land inhabited by the descendants of one of Abraham's sons with his concubine Keturah. Job had been an inhabitant of those lands, and he knew Jehovah.
6) Esau, one of Isaac's twins, had his own lands apart from those that much later his brother Jacob's (Israel) descendants received in Canaanite lands. (Deut. 2:12)
7) The name of Jehovah became very famous due to the disasters He caused in the Egyptian empire of the days of Moses. This news spread throughout the earth, and when the Israelites began to conquer Canaan 40 years after leaving Egypt, many people already feared their God.
8) All the battles fought by Jehovah using Israel, contributed to the fact that He was spoken of in many kingdoms close to the area.
