“The three sons of Benjamin were Bela, Becher, and Jediael.”
Benjamin, the youngest of the sons of Jacob, had a number of sons. Based on Genesis, chapter 46, he had 10 sons. In Numbers, chapter 26, he had 5 sons, while here he has 3 sons. There is a substantial difference between the lists of the descendants of Benjamin in Genesis, Numbers, and here. In Genesis, Benjamin (Benjaminites) had 10 sons, including Bela (the Belaites) and Becher (Becherites). Only 1 name is the same in all 3 lists, (1) Bela. Bela was another name for the place called Zoar in Genesis. In fact, today there are many places throughout the world named Bela. There are 2 other people named Bela in other biblical tales. Those missing from the list in Numbers are (2) Becher, Gera, Naaman, Ehi, Rosh, Muppim, Huppim, and Ard. Becher is listed as a son of Ephraim, so that may be why he is not in Numbers. In other books of the Bible, Gera is listed as a son of Benjamin, but not in Numbers. Naaman and Ard are listed as the descendants of Bela, not of Benjamin as in Genesis. The mention of Ehi and Muppim in Genesis are the only mentions of these two in the biblical works. Rosh is some sort of kingdom in later works. It is possible that Hupham is just another way of saying Huppim, since they are both listed only once in Numbers and Genesis. Both Ahiram and Shephupham are only listed in Numbers, and in no other works. Here (3) Jediael was not listed in Genesis or Numbers. Perhaps he is the same as the Ashbel that is found in both Genesis and Numbers, but not here. Certainly this is not as clear as the sons of Issachar.
