In last week’s reading, G‑d instructed Moshe to give the daughters of the deceased Zelophehad his portion in the land of Israel. The elders of Zelophehad’s tribe now protested that this would cause Zelophehad’s sons — who could possibly be of another tribe — to inherit their mother’s properties, thus possibly transferring land from the portion of their tribe to another. G‑d therefore instructs Zelophehad’s daughters to marry men from their own tribe, so the land they inherit will remain in their ancestral tribe.
