If Paul spoke, read, wrote, and understood Hebrew, then he knew what the original Hebrew words were in Deuteronomy 32:8, which means that he must have known that "the sons of Adam" were separated from "the children of Israel" when God "set the bounds of the people according to the number of the children of Israel".

 

Deu 32:7 Remember the days of old, consider the years of many generations: ask thy father, and he will shew thee; thy elders, and they will tell thee.

Deu 32:8 When the most High divided to the nations their inheritance, when he separated the sons of Adam, he set the bounds of the people according to the number of the children of Israel.

Deu 32:9 For the LORD'S portion [is] his people; Jacob [is] the lot of his inheritance.

Deu 32:10 He found him in a desert land, and in the waste howling wilderness; he led him about, he instructed him, he kept him as the apple of his eye.

Deu 32:11 As an eagle stirreth up her nest, fluttereth over her young, spreadeth abroad her wings, taketh them, beareth them on her wings:

Deu 32:12 [So] the LORD alone did lead him, and [there was] no strange god with him.

 

Act 17:24 God that made the world and all things therein, seeing that he is Lord of heaven and earth, dwelleth not in temples made with hands;

Act 17:25 Neither is worshipped with men's hands, as though he needed any thing, seeing he giveth to all life, and breath, and all things;

Act 17:26 And hath made of one blood all nations of men for to dwell on all the face of the earth, and hath determined the times before appointed, and the bounds of their habitation;

Act 17:27 That they should seek the Lord, if haply they might feel after him, and find him, though he be not far from every one of us:

Act 17:28 For in him we live, and move, and have our being; as certain also of your own poets have said, For we are also his offspring.

Act 17:29 Forasmuch then as we are the offspring of God, we ought not to think that the Godhead is like unto gold, or silver, or stone, graven by art and man's device.
