Because of this [statement] the law eluded him, etc. Because Moshe likened himself to Hashem: For it is written, “For justice belongs to Hashem,” and afterwards it is written, “And the matter that will be too difficult for you, present to me,” as if Moshe himself were Hashem. Therefore, the laws pertaining to inheritance which are a simple matter eluded him. For everyone knows that if a man has no sons, then a daughter inherits instead of a son. For Rachel and Leah said (Bereishis 31:14), “Do we have a portion anymore, etc,” meaning: We do not share the inheritance along with the males. Yet, this eluded Moshe. Rashi did not explain that because of this statement the law regarding the woodchopper, or regarding the ritually impure eluded him — for those are not simple [laws], and therefore Moshe did not know. But the laws regarding inheritance are simple.
