Mark 9:33-35

331They came to Capernaum; and when He was in 2the house, He began to question them: “What were you discussing on the way?”

34But they kept silent, for on the way 3they had discussed with one another which of them was the greatest.

35And sitting down, He called the twelve and said to them, “4If anyone wants to be first, he shall be last of all and servant of all.”
