Bereshis 10:31 Meaning and Commentary

Genesis 10:31

These are the sons of Shem
His sons, and grandsons, and great grandsons, in all twenty six, no doubt but there were many more, but these are only mentioned; for none of the sons of Elam, Ashur, and Lud, are named, and but one of Arphaxad's, and one of Salah's, and two of Eber's, and none of Peleg's; when it is not to be questioned but they had many, as is certain of Arphaxad, Salah, Eber, and Peleg, ( Genesis 11:13-15 Genesis 11:17 Genesis 11:19 )

after their families, after their tongues, in their lands, after
their nations:
from hence sprung various families at first, and these of different languages upon the confusion of Babel, which thenceforward formed different nations, dwelt in different lands; which have been pointed at as near as we can at this distance, and with the little helps and advantages we have: it seems from hence that Shem's posterity were of different languages as well as those of Ham and Japheth.
