Talmud su Isaia 6:3

Pursue peace. How so? This teaches that a person should pursue peace in Israel between everyone (in the way that Aaron would pursue peace in Israel between everyone, as it says [Psalms 34:15], “Turn from evil, and do good; seek peace and pursue it.”
Rabbi Shimon ben Elazar would say:) If a person stays quietly in his place, how can he pursue peace in Israel between everyone? [Rather, he should go out from his place and into the world and pursue peace in Israel,] as it says, “Seek peace and pursue it.” How does this work? Seek it where you are, and pursue it in some other place. Even the Holy Blessed One made peace in the heights, for He did not call ten angels Gabriel, ten angels Michael, ten angels Uriel, and ten angels Raphael, in the way humans do, calling ten people Reuben, ten people Shimon, ten people Levi, and ten people Judah. For if He had done as humans do, when He called one of them, they all would have come, and then become jealous of one another. So instead, He called only one angel Gabriel and one Michael, and when He calls any one of them, [that angel] comes before Him, and He dispatches the angel wherever He desires. And how do we know that they revere one another, and respect one another, and are humbler than human beings? Because when they open their mouths to sing a song, one of them says to the other: You should begin, for you are greater than I, and then the other one says: No, you should begin, for you are greater than I. This is not the way it is with human beings. Every person says to another: I am greater than you, and the other person responds: No, I am greater than you.
And some say they spoke in groupings [of angels]. One grouping would say to the other: You all should begin, for you are greater than we, as it says (Isaiah 6:3), “And this one called out to that one and said….”
