Mark 10:43

41When the ten heard it, they began to be indignant toward James and John.

42Jesus summoned them and said to them, “You know that they who are recognized as rulers over the nations lord it over them, and their great ones exercise authority over them.

43But it shall not be so among you, but whoever wants to become great among you shall be your servant.

44Whoever of you wants to become first among you shall be bondservant of all.

45For the Son of Man also came not to be served but to serve, and to give his life as a ransom for many.”
