Genesis 10:24 - Ellicott's Commentary On The Whole Bible

Arphaxad begat Salah. — Heb., Shelah. The rest of the chapter is devoted to giving an account of the settlements of the Joktanite Arabs, who formed only one, apparently, of the races sprung from Arphaxad, as in this table even the Hebrews are omitted, although Eber’s birth is given with the view of showing that the right of primogeniture belonged not to Joktan, but to Eber. The name Arphaxad, as we have seen (Genesis 10:22), at present defies all explanation. For the rest, see the Tôldôth Shem, Genesis 11:10-26.
