Genesis 10

11. Out of that land went forth Asshur--or, as the Margin has it, "He [Nimrod] at the head of his army went forth into Assyria," that is, he pushed his conquests into that country.
and builded Nineveh--opposite the town of Mosul, on the Tigris, and the other towns near it. This raid into Assyria was an invasion of the territories of Shem, and hence the name "Nimrod," signifying "rebel," is supposed to have been conferred on him from his daring revolt against the divine distribution.

21. Unto Shem--The historian introduces him with marked distinction as "the father of Eber," the ancestor of the Hebrews.

23. Aram--In the general division of the earth, the countries of Armenia, Mesopotamia, and Syria, fell to his descendants.

24. Arphaxad--The settlement of his posterity was in the extensive valley of Shinar, on the Tigris, towards the southern extremity of Mesopotamia, including the country of Eden and the region on the east side of the river.

25. Peleg; for in his days was the earth divided--After the flood ( Genesis 11:10-16 ) the descendants of Noah settled at pleasure and enjoyed the produce of the undivided soil. But according to divine instruction, made probably through Eber, who seems to have been distinguished for piety or a prophetic character, the earth was divided and his son's name, "Peleg," was given in memory of that event (see Deuteronomy 32:8 , Acts 17:26 ).

32. These are the families of the sons of Noah, after their generations, in their nations, &c.--This division was made in the most orderly manner; and the inspired historian evidently intimates that the sons of Noah were ranged according to their nations, and every nation ranked by its families, so that every nation had its assigned territory, and in every nation the tribes, and in every tribe the families, were located by themselves.
