Matthew 20:25–28
[25] But Jesus called them to him and said, “You know that the rulers of the Gentiles lord it over them, and their great ones exercise authority over them. [26] It shall not be so among you. But whoever would be great among you must be your servant, [27] and whoever would be first among you must be your slave, [28] even as the Son of Man came not to be served but to serve, and to give his life as a ransom for many.” (ESV)
