Mark 10:42-45

42 But Jesus called them to Himself and said to them, "You know that those who are considered rulers over the Gentiles lord it over them, and their great ones exercise authority over them.

43 Yet it shall not be so among you; but whoever desires to become great among you shall be your servant.

44 And whoever of you desires to be first shall be slave of all.

45 For even the Son of Man did not come to be served, but to serve, and to give His life a ransom for many."
