Mark 9:33-39

³³Then He came to Capernaum. And being in the house He asked them, “What were you disputing about with one another on the road?”

³⁴But they were silent, for on the road they had discussed with one another who was the greatest.

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

³⁶And taking a child, He stood him in their midst. And taking him in His arms, He said to them,

³⁷“Whoever receives one of these little children in My name receives Me; and whoever receives Me, receives not Me, but Him who sent Me.”

³⁸Now John answered Him, saying, “Teacher, we saw someone who does not follow with us casting out demons in Your name, and we forbade him because he does not follow with us.”

³⁹But Jesus said, “Do not forbid him, for there is no one who will perform a miracle in My name that will be able to soon speak evil of Me.
