Mark 10:41-45

Hearing this, the [other] ten became indignant with James and John. Calling them to Himself, Jesus said to them, “You know that those who are recognized as rulers of the Gentiles lord it over them; and their powerful men exercise authority over them [tyrannizing them]. But this is not how it is among you; instead, whoever wishes to become great among you must be your servant, and whoever wishes to be first and most important among you must be slave of all. For even the Son of Man did not come to be served, but to serve, and to give His life as a ransom for many.”
