דברי הימים א, פרק י״א, פסוק מ״ב

Adina son of Shiza, a prominent figure from the tribe of Reuben, emerged as a powerful leader defined by his rise to greatness and the dedicated warriors who gathered around him. Over time, his influence grew to the point where he was appointed as the official head of his tribe [ביאור שטיינזלץ].

A defining feature of his leadership was a core group of thirty men who stood by his side. These were individuals who joined his ranks and remained closely associated with him [רלב״ג, ביאור שטיינזלץ]. They were not merely companions but loyal followers who relied on his guidance and trusted his direction [מצודת דוד]. Although thirty men are noted as part of his loyal band, not all of them are listed by name. Immediately following the mention of this group, only fourteen specific individuals are actually recorded [רלב״ג].
