דברי הימים א, פרק כ״ד, פסוק כ״ט

Family leadership within the ancient tribes often defined the very identity of a household. The ancestral house of Kish experienced a significant shift in its structure that ultimately changed how the entire family was recognized. The descendants of Kish came under the guidance of a man named Jerahmeel, who stepped up to lead the family [ביאור שטיינזלץ].

Because Jerahmeel took on such a prominent role, the family's public identity shifted. The original household, which had previously been known by the name of Kish, was renamed. From that point forward, the family was called after Jerahmeel, who was himself one of Kish's descendants [מצודת דוד].
