Hillel said: Be of the disciples of Aaron, loving peace and pursuing peace, loving humankind and drawing them close to the Torah. (Ethics of our Ancestors 1:12). It is striking that Aaron, the first kohen/priest is known as someone who not just loves peace but pursues it (rodeif). It is also worth noting that Aaron sought peace not just for the Jewish people. Hillel uses the word beriyot, which means all living creatures. Peace cannot be limited –it has to include everyone for it to peace.
