The daughters of Zelophehad approached Moses to see if they could be given a portion in the land. And Moses brought forward their case before the LORD.The Midrash records two opposing views of why Moses turned to God. One view is that since Moses had told the people whatever is difficult you can bring to me, he was forced to demonstrate that he did not have all the answers and had to ask God. Another view is that Moses knew the answer. However, first the daughters directed their question to the bottom rung of leadership, who sent them to the next rung and so it continued until the question reached Moses. At that point his great humility did not allow him to answer a question that nobody else was willing to answer and so Moses brought forward their case before the LORD.
