"God" does not refer to a single being, and the Trinity is not foreign to the OT; the Angel of the Lord is called "Yahweh" on multiple occasions—such as when Yahweh turns His face toward Gideon—Angels, demons, men, the divine persons, the divine essence are all referred to as God
I find these verses particularly unique in the argument for a universal all-loving God. In the older reading of Deuteronomy 32:8–9, Elyon, the Most High, divides the nations among the divine beings, while Yahweh receives Jacob, Israel, as his allotted portion. Each deity has its nation, and the text itself places Yahweh on the receiving end of Elyon’s division.
This preserves an older divine-council worldview where Yahweh appears as Israel’s allotted deity rather than simply being presented as the universal God above the entire arrangement. Yet Yahweh is later identified as the God of all nations and the same God worshipped by Jesus. So where exactly do we find ourselves? An eternally universal God revealed consistently from the beginning, or a theology that developed from an older world of national gods into the universal God of later Judaism and Christianity?
