Genesis 11:10 Meaning and Commentary

Genesis 11:10

These are the generations of Shem
Or a genealogy of the posterity of Shem; not of all of them, only of those of the line which led to Abraham, by which might appear the true line in which the Messiah from Adam through Abraham sprung:

Shem was one hundred years old, and begat Arphexad two years after
the flood;
by which it is pretty plain that he was younger than Japheth; (See Gill on Genesis 10:21) of Arphaxad his son, (See Gill on Genesis 10:22).
