Eber in Fausset's Bible Dictionary

Son of Salah, great grandson of Shem (Genesis 10:21-24; 1 Chronicles 1:19; Numbers 24:24, where the "Eber" whom "ships from Chittim shall afflict" represents not the Hebrew, but in general the western descendants of Shem, sprung from Arphaxad, Lud, and Aram; the posterity of Abraham who descended from Eber through Peleg, and also the descendants of Eber through Joktan. As "Asshur" represented the Shemites who dwelt in the far East, including Elam, so Eber represents the western Shemites.
