במדבר, פרק ג׳, פסוק כ״ד

Leading a major family within the Israelite camp required a clear and formal structure. As the Gershonite family organized for their specific duties, their leadership was carefully established. The title of leader given to Eliasaph son of Lael goes beyond a simple statement of fact. Rather than merely describing his existing status within the community, it serves as an active, official appointment. According to [העמק דבר], this designation acts as a direct command, formally installing him as the head of the Gershonite family and officially charging him with the responsibility to lead them.
