This section explains where the ancient Near Eastern nations came from. Ham was at the center (10:6–20)while the descendants of Japheth and Shem spread out to the surrounding regions of Greece, Crete, Asia Minor, Mesopotamia, Madai, the Arabian peninsula, and northeast Africa.
The list is selective in focusing on nations important to Israel. The 70 names (seven times ten) indicate completeness (see 46:27; Deuteronomy 32:8). These names represent the whole world, which Abraham's descendants would later bless (Genesis 18:18).
Although Shem is mentioned first in 10:1, he is addressed last in the Table because of his connection to Abram (10:21–31; 11:10–32; 12:1). Although God established the boundaries of all nations (see Deuteronomy 32:8; Amos 9:7; Acts 17:26), Israel was his special creation (a small group of 70 people; Genesis 46:27). God called them to be a blessing to a world of 70 nations (see 12:3).
