I ran across a Greek myth that said the world was governed by 70 sons of God, which tied in neatly with his exposition of Deut. 32:8, so I sent him an email, which he never replied to (he said he would on occasion). Never heard from him and wondered why. I found out later, his medical condition had started and I don’t think he was interested in such details.
The Ugaritic texts also refer to the number 70, in the context of the divine family or council of El, the high god of the Canaanite pantheon.
While the number is not emphasized repeatedly or elaborated in mythological detail, it does appear clearly and meaningfully, and it directly informs the biblical worldview reflected in Deuteronomy 32:8–9.
Also worth noting, the Ugaritic texts strongly support the interpretation of Genesis 6:1–4, where the “sons of God” (bene ha’elohim) are understood to be divine beings or angels, not human rulers or descendants of Seth.
