Mark 9:33-35

³³They came to Capernaum; and when He was in the house, He began to question them, “What were you discussing on the way?” ³⁴But they kept silent, for on the way they had discussed with one another which of them was the greatest. ³⁵Sitting down, He called the twelve and said to them, “If anyone wants to be first, he shall be last of all and servant of all.”
