Mark 9:33-37King James Version (KJV)
33 And he came to Capernaum: and being in the house he asked them, What was it that ye disputed among yourselves by the way?
34 But they held their peace: for by the way they had disputed among themselves, who should be the greatest.
35 And he sat down, and called the twelve, and saith unto them, If any man desire to be first, the same shall be last of all, and servant of all.
36 And he took a child, and set him in the midst of them: and when he had taken him in his arms, he said unto them,
37 Whosoever shall receive one of such children in my name, receiveth me: and whosoever shall receive me, receiveth not me, but him that sent me.
