עזרא, פרק ח׳, פסוק י״ט

The journey back to the land of Israel required dedicated individuals to support the community. As the record of those making the journey expands, it specifically details the Levites who joined the returning exiles [ביאור שטיינזלץ]. The messengers who were sent out successfully gathered these crucial members, bringing Hashabiah back with them to join the group [אבן עזרא].

Alongside these leaders came their close associates. The mention of their brothers does not refer to actual biological siblings, but rather to their friends, partners, and colleagues. Furthermore, even though the description is phrased as if these companions belonged to only one of the leaders, it actually applies to both of them. The account simply keeps the description brief, relying on the reader to easily understand this natural partnership [מצודת דוד].
