Matthew 18:2-6

2And Jesus called a little child unto him, and set him in the midst of them,

3And said, Verily I say unto you, Except ye be converted, and become as little children, ye shall not enter into the kingdom of heaven.

4Whosoever therefore shall humble himself as this little child, the same is greatest in the kingdom of heaven.

5And whoso shall receive one such little child in my name receiveth me.

6But whoso shall offend one of these little ones which believe in me, it were better for him that a millstone were hanged about his neck, and that he were drowned in the depth of the sea.
