Matthew 18:1-6

1 At that time the disciples came to Jesus, saying, "Who is the greatest in the kingdom of heaven?"

2 And calling to him a child, he put him in the midst of them,

3 and said, "Truly, I say to you, unless you turn and become like children, you will never enter the kingdom of heaven.

4 Whoever humbles himself like this child, he is the greatest in the kingdom of heaven.

5 "Whoever receives one such child in my name receives me;

6 but whoever causes one of these little ones who believe in me to sin, it would be better for him to have a great millstone fastened round his neck and to be drowned in the depth of the sea.
