Easton's Bible Dictionary (1897)
First-born; a youth, the second son of Benjamin (Gen. 46:21), who came down to Egypt with Jacob. It is probable that he married an Ephraimitish heiress, and that his descendants were consequently reckoned among the tribe of Ephraim (Num. 26:35; 1 Chr. 7:20, 21). They are not reckoned among the descendants of Benjamin (Num. 26:38).
