במדבר, פרק כ״ו, פסוק ל׳

As families grow over generations, they often reach a point where smaller branches establish their own unique identities. The lineage of Gilead captures this natural evolution of family structures. Certain descendants, specifically Iezer and Helek, went through a process of separation. They stepped out from the broader family umbrella to establish independent households, becoming the founders of the Iezerite and Helekite families [ביאור שטיינזלץ]. This transition marks a significant shift, as these groups broke away from their father's original household and began to be recognized by their own distinct names.

However, this branching out was not universal. Many other descendants did not separate into new, independent groups. Instead, they remained unified, continuing to be known collectively under the original, general family name of the Gileadites [העמק דבר].
