Mattityahu 20:26-28

But it will not be thus among you. For whoever wishes to be gadol among you will become your mesharet (servant, minister). And whoever wishes among you to be rishon (first) will be your eved (servant). Just as the Bar Enosh did not come to be served, to be ministered to, but to serve, to minister, and to give his neshamah, his nefesh, as a kofer (ransom, pedut) LARABBIM (for the sake of many, for the Geulah Redemption of many).
