The careful organization of the priesthood involved appointing dedicated leaders to oversee the various families. In this arrangement, Zichri was chosen to direct the priestly group of Abijah. A unique situation occurred with the groups of Miniamin and Moadiah, as a single man named Piltai was appointed to lead them [ביאור שטיינזלץ].
This shared leadership was not a coincidence. This specific priestly division was actually known by both titles simultaneously, functioning as a single unit under a combined name [מצודת דוד]. These two family titles are simply alternate versions of the names Mijamin and Maadiah, which were already recorded earlier in the registry [רלב״ג].
