whoever wants to be first must be last of all and servant of all

The Greek that is translated as “whoever wants to be first must be last of all and servant of all” or similar in English is translated in Tzotzil as “If anyone wants to be thought of as the most important, let him humble himself, let him help all people,” in Chuj as “If there is one man wants to lift up himself among you, he must make himself lowly before you. He must enter as the servant of you all, he said,” and in Choapan Zapotec as “If a person wants to command his fellow-men, he must consider himself to be as a person who has no authority, let him work without pay for anyone.” (Source: B. Moore / G. Turner in Notes on Translation 1967, p. 1ff.)
