Mark 10:42

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.

Luke 22:25-27

22:25 So Jesus said to them, “The kings of the Gentiles lord it over them, and those in authority over them are called ‘benefactors.’ 22:26 Not so with you; instead the one who is greatest among you must become like the youngest, and the leader like the one who serves. 22:27 For who is greater, the one who is seated at the table, or the one who serves? Is it not the one who is seated at the table? But I am among you as one who serves.
