Why Uzziel the Uncle of Aaron Pursued Peace Like Aaron

"And Moses called to Mishael and to Elzaphan, the sons of Uzziel the uncle of Aaron." What does Scripture teach by saying "the uncle of Aaron"? Has it not already been stated, "And the sons of Kohath: Amram, and Izhar, and Hebron, and Uzziel" (Exodus 6:18)? It is to liken the deeds of Uzziel to Aaron: just as Aaron pursued peace in Israel — as it is said, "And all the house of Israel wept for Aaron thirty days" (Numbers 20:29), even the women, which was not said of Moses, for over Moses only the males wept, but over Aaron the males and the females wept — so too Uzziel pursued peace like Aaron. And so it says of Aaron, "in peace and uprightness he walked with Me" (Malachi 2:6), that he did not question the ways of the Omnipresent.
