of Benjamin. In the parallel place of Genesis, ten sons of Benjamin are reckoned, Bela, Becher, Ashbel, Gera, Naaman, Ehi, Rosh, Muppim, Huppim, and Ard; and in Numbers, five only are mentioned, Bela, Ashbel, Ahiraim, Shupham, and Hupham; and Ard and Naaman are said to be the sons of Bela, and consequently Benjamin's grandsons. In the beginning of the following chapter, also, five are only mentioned, Bela, Ashbel, Aharah, Nohah, and Rapha; and Addar, Gera, Abihud, Abishua, Naaman, Ahoha, another Gera, Shephuphan, and Huram, are all represented as grandsons, not sons of Benjamin: hence we see that in many cases, grandsons are called sons, and both are often confounded in the genealogical tables. It seems, also, that the persons mentioned in the following verses were neither sons nor grandsons of Bela and Becher, but distinguished persons among their descendants.
