Matthew 20:25-28

20:25 But Jesus called them and said, “You know that the rulers of the Gentiles lord it over them, and those in high positions use their authority over them. 20:26 It must not be this way among you! Instead whoever wants to be great among you must be your servant, 20:27 and whoever wants to be first among you must be your slave – 20:28 just as the Son of Man did not come to be served but to serve, and to give his life as a ransom for many.”

Mark 10:41-45

10:41 Now when the other ten heard this, they became angry with James and John. 10:42 Jesus called them and said to them, “You know that those who are recognized as rulers of the Gentiles lord it over them, and those in high positions use their authority over them. 10:43 But it is not this way among you. Instead whoever wants to be great among you must be your servant, 10:44 and whoever wants to be first among you must be the slave of all. 10:45 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.”
