Deuteronomy 32:8
7 Remember the ancient days; bear in mind the years of past generations. Ask your father and he will inform you, your elders, and they will tell you. 8 When the Most High gave the nations their inheritance, when he divided up humankind, he set the boundaries of the peoples, according to the number of the heavenly assembly. 9 For the Lord’s allotment is his people, Jacob is his special possession. 10 The Lord found him in a desolate land, in an empty wasteland where animals howl. He continually guarded him and taught him; he continually protected him like the pupil of his eye.
Jubilees 15:18
17 All the descendants of his sons would become nations and be numbered with the nations. But one of Isaac's sons would become a holy progeny and would not be numbered among the nations, 18 for he would become the share of the Most High. All his descendants had fallen into that share which God owns so that they would become a people whom the Lord possesses out of all the nations; and that they would become a kingdom, a priesthood, and a holy people. 19 Then we went on our way and told Sarah all that we had reported to him. The two of them were extremely happy.

The Interpolator is here restating the then-common understanding of Deuteronomy 32:8-9: God appointed various angels (“sons of God”—this phrase appears in place of “sons of Israel” in the Septuagint and other ancient versions of Deuteronomy 32:8) to rule over the other nations of the world, but He rules directly over Israel, without an angelic intermediary ..."
