Markos 10:42-45

And having summoned them, Rebbe, Melech HaMoshiach says to them, You have daas that among the Goyim those whom they recognize as their moshlim (rulers) domineer them and their Gedolim exercise authority over them. However, it is not so among you. He who wishes to become gadol among you must be your mesharet. And whoever wishes to be first among you must be eved of all. For even the Bar Enosh did not come to be served but to serve and to give his NEFESH as a kofer (ransom, pedut) LARABBIM (for many, for the Geulah [Redemption] of many).
