Mark 9:
30They went on from there and passed through Galilee. And he would not have any one know it; 31for he was teaching his disciples, saying to them, "The Son of man will be delivered into the hands of men, and they will kill him; and when he is killed, after three days he will rise."  32But they did not understand the saying, and they were afraid to ask him.  33And they came to Caper'na-um; and when he was in the house he asked them, "What were you discussing on the way?"  34But they were silent; for on the way they had discussed with one another who was the greatest.  35And he sat down and called the twelve; and he said to them, "If any one would be first, he must be last of all and servant of all."  36And he took a child, and put him in the midst of them; and taking him in his arms, he said to them,  37"Whoever receives one such child in my name receives me; and whoever receives me, receives not me but him who sent me."
