Mark 9:33-35

Jesus and his followers went to Capernaum. They went into a house, and Jesus said to them, “I heard you arguing on the way here today. What were you arguing about?” But the followers did not answer, because their argument on the road was about which one of them was the greatest. Jesus sat down and called the twelve apostles to him. He said, “Whoever wants to be the most important must make others more important than themselves. They must serve everyone else.”
