BEN-AMMI (‘son of my blood-relative’ or ‘son of my father’s kinsman’). The story ( Genesis 19:1-38 ) purports to explain the name Ammon ( Genesis 19:38 ). Notwithstanding the fact that incestuous marriages were common amongst these people, it is most likely that the narrative is a product of the bitter hatred which was excited by prolonged contests for the territory E. of Jordan.
