במדבר, פרק ל״ד, פסוק כ״ט

God's instructions for the division of the Promised Land require careful leadership to ensure fairness and order. The appointed tribal leaders were given the heavy responsibility of overseeing this exact process. They were tasked with the practical distribution of the territory that fell to their tribe by lot [שד״ל]. Their specific duty was to make sure that every single person received their proper portion [ביאור שטיינזלץ], essentially handing over the land directly to each individual [העמק דבר].

The primary approach among commentators is that the leaders were responsible for actively causing the people to inherit and dividing the land according to its groups [רש״י]. While the nature of this responsibility might initially seem to blur the lines between simply receiving land and actively distributing it [ברכת אשר על התורה], a deeper look clarifies their exact duties. The leaders' role was specifically tied to the active process of casting the lots. They had a twofold mission: first, to advocate for and secure a good portion of land for their tribe, and second, to manage the actual casting of the lots. Both the selection of the land and the administration of the lottery were to be handled exclusively by these appointed individuals [גור אריה].
