Allocating the Promised Land to the Israelites was far more than a simple distribution of real estate or a political compromise. It was a deeply complex process that merged divine guidance, demographic reality, and historical justice. To prevent disputes and demonstrate that the outcome was entirely the will of God, the exact location where each tribe would settle was determined by a lottery. However, this lottery only dictated the geographical placement of the tribes. The actual size of each territory was carefully adjusted according to population, ensuring that larger tribes received expansive areas while smaller tribes received proportionally less [רמב״ן, שד״ל, רלב״ג, חזקוני, העמק דבר].
The drawing of the lots was not left to chance but was a miraculous event guided by divine inspiration. Eleazar the High Priest, wearing the sacred breastplate, stood before two urns containing the names of the tribes and the regions of the land. Before drawing the lots, he would prophesy exactly which territory would emerge for each tribe. As the lots were drawn, the match was completely perfect, and the slips themselves miraculously called out the connection between the tribe and its newly assigned home [רבנו בחיי, תורה תמימה, חומש קה״ת]. Furthermore, absolute fairness was maintained regarding the quality of the land. If a tribe drew a less fertile region, they received financial compensation from a tribe that was awarded premium, highly productive land [רבנו בחיי].
While the lottery governed the general distribution, a notable exception was made for two specific leaders. Joshua and Caleb were entirely excluded from this lottery system. Instead of drawing lots, they received their specific territories directly through a command from God [רש״י, חזקוני, תורה תמימה, מלבי״ם, שפתי חכמים].
Determining exactly who held the legal rights to the land introduces a profound concept. While a straightforward understanding suggests the land was simply divided among the twelve tribes [רמב״ן], the primary approach among commentators views the inheritance as belonging to the original generation that left Egypt. This creates an extraordinary legal mechanism where, effectively, the dead inherit from the living. Although the physical land was distributed to the younger generation entering the land, the legal ownership reverted back to their fathers and grandfathers who had left Egypt. The territories of the younger generation were grouped together, divided equally among the brothers of the previous generation, and only then inherited back down by the current generation [רש״י, אור החיים, ריב״א, מזרחי, ברטנורא].
This intricate legal structure served to fulfill God's original promise. He had promised the land to the generation that departed Egypt, and even though they sinned and died in the desert, His word remained intact. By conceptually returning the inheritance to them, God fulfilled His promise [שפתי חכמים, גור אריה]. It also served as a profound mark of respect for that desert generation; despite their flaws, they successfully raised a faithful, worthy generation to enter the land [רש״ר הירש]. Finally, the strict reliance on ancestral tribal lineage meant that converts and freed slaves were excluded from this specific distribution. Because they did not share a direct ancestral link to the sons of Jacob who left Egypt, they did not receive a portion in the division of the land [רש״י, רבנו בחיי, חזקוני, תורה תמימה].
