"Most English Bibles do not read 'according to the number of the sons of God' in Deuteronomy 32:8. Rather, they read 'according to the number of the sons of Israel.' The difference derives from disagreements between manuscripts of the Old Testament. 'Sons of God' is the correct reading, as is now known from the Dead Sea Scrolls.
Frankly, you don’t need to know all the technical reasons for why the 'sons of God' reading in Deuteronomy 32:8-9 is what the verse originally said. You just need to think a bit about the wrong reading, the 'sons of Israel.'
Deuteronomy 32:8-9 harks back to events at the Tower of Babel, an event that occurred before the call of Abraham, the father of the nation of Israel. This means that the nations of the earth were divided at Babel before Israel even existed as a people. It would make no sense for God to divide up the nations of the earth 'according to the number of the sons of Israel' if there was no Israel."

Summary Statement
Through Jesus Christ, God is gathering the nations back to Himself- Both disinherited Gentiles and wayward Jews. “Faith” makes for equal-footing before YHWH, with acceptance being gained by the bloodwork of Jesus Christ.
