Mark 9:33-37
33They came to Capernaum; and when He was in the house, He began to question them, “What were you discussing on the way?” 34But they kept silent, for on the way they had discussed with one another which of them was the greatest. 35Sitting down, He called the twelve and said to them, “If anyone wants to be first, he shall be last of all and servant of all.” 36Taking a child, He set him before them, and taking him in His arms, He said to them, 37″Whoever receives one child like this in My name receives Me; and whoever receives Me does not receive Me, but Him who sent Me.”
