This verse, along with surrounding verses, lists families of the Nethinims. Commentators explain these were not priests but 'temple-bondsmen' who performed the most laborious duties at the sanctuary. Their history as temple servants was long, originating from groups like the Gibeonites (Joshua 9:23) and others dedicated to this service. Their careful inclusion in the record highlights God's remembrance of every person who serves Him, regardless of their rank.
