Luke 9:46-50

46And a reasoning came in amongst them, who should be [the] greatest of them.

47And Jesus, seeing the reasoning of their heart, having taken a little child set it by him,

48and said to them, Whosoever shall receive this little child in my name receives me, and whosoever shall receive me receives him that sent me. For he who is the least among you all, he is great.

49And John answering said, Master, we saw some one casting out demons in thy name, and we forbad him, because he follows not with us.

50And Jesus said to him, Forbid [him] not, for he that is not against you is for you.
