Luke 9:46-50

46Then his disciples began arguing about which of them was the greatest.

47But Jesus knew their thoughts, so he brought a little child to his side.

48Then he said to them, “Anyone who welcomes a little child like this on my behalf welcomes me, and anyone who welcomes me also welcomes my Father who sent me. Whoever is the least among you is the greatest.”

49John said to Jesus, “Master, we saw someone using your name to cast out demons, but we told him to stop because he isn’t in our group.”

50But Jesus said, “Don’t stop him! Anyone who is not against you is for you.”
