Mark 9:33-39

³³They came to Capernaum. When Jesus had gone into the house, he asked them, “What were you discussing on the way?”

³⁴But they were silent; for on the way they had been arguing with one another which was the greatest.

³⁵Sitting down, Jesus called the Twelve and said, “If anyone wishes to be first, he must be last of all, and servant of all.”

³⁶Then Jesus took a little child, and placed it in the middle of them. Taking it in his arms, he said to them,

³⁷“Anyone who, for the sake of my name, welcomes even a little child like this is welcoming me, and anyone who welcomes me is welcoming not me, but him who sent me as his messenger.”

³⁸“Teacher,” said John, “we saw a man driving out demons by using your name, and we tried to prevent him, because he did not follow us.”

³⁹“None of you must prevent the man,” answered Jesus, “for no one will use my name in working a miracle, and yet find it easy to speak evil of me.
