Benjamin’s sons were, – Bela – Becher – Ashbel – Gera – Nayman – Ehi – Rosh – Muppim – Huppim – Ard
All those were the sons and grand-sons that Jacob had with his wife Rachel. There were 14 of them.
Then Jacob said, “Benjamin’s tribe will be like a wild dog that is really hungry. In the morning, they will kill their enemies and grab all their good things, and in the night time, they will share those good things with each other.”
