Mark 9:33-40

33And they came to Capernaum: and when he was in the house he asked them, What were ye reasoning in the way?

34But they held their peace: for they had disputed one with another in the way, who was the greatest.

35And he sat down, and called the twelve; and he saith unto them, If any man would be first, he shall be last of all, and minister of all.

36And he took a little child, and set him in the midst of them: and taking him in his arms, he said unto them,

37Whosoever shall receive one of such little children in my name, receiveth me: and whosoever receiveth me, receiveth not me, but him that sent me.

38John said unto him, Master, we saw one casting out devils in thy name: and we forbade him, because he followed not us.

39But Jesus said, Forbid him not: for there is no man which shall do a mighty work in my name, and be able quickly to speak evil of me.

40For he that is not against us is for us.
