Luke 9:43-48

And they were all amazed at the mighty power of God. But while they wondered every one at all things which Jesus did, he said unto his disciples, Let these sayings sink down into your ears: for the Son of man shall be delivered into the hands of men. But they understood not this saying, and it was hid from them, that they perceived it not: and they feared to ask him of that saying. Then there arose a reasoning among them, which of them should be greatest. And Jesus, perceiving the thought of their heart, took a child, and set him by him, and said unto them, Whosoever shall receive this child in my name receiveth me: and whosoever shall receive me receiveth him that sent me: for he that is least among you all, the same shall be great.
