Mark 9:32-37

32But they did not understand what he meant and were afraid to ask him about it. 33They came to Capernaum. When he was in the house, he asked them, “What were you arguing about on the road?”

35Sitting down, Jesus called the Twelve and said, “Anyone who wants to be first must be the very last, and the servant of all.” 36He took a little child whom he placed among them. Taking the child in his arms, he said to them,

37“Whoever welcomes one of these little children in my name welcomes me; and whoever welcomes me does not welcome me but the one who sent me.”
