This noun describes an attendant or servant, particularly one who serves willingly and devotedly. Classical usage ranged from military squires and personal attendants to worshipers serving deities. It suggests more personal service than the common word for slave (δοῦλος), emphasizing willing devotion and companionship in service. Hebrews uses it to describe Moses's role in God's house—a trusted servant administering God's household. The term carries dignity while acknowledging subordinate position, appropriate for describing honored service to a superior.
