Mark 9:35-37

And He sat down, called the twelve, and said to them, “If anyone desires to be first, he shall be last of all and servant of all.” Then He took a little child and set him in the midst of them. And when He had taken him in His arms, He said to them, “Whoever receives one of these little children in My name receives Me; and whoever receives Me, receives not Me but Him who sent Me.”
