Matthew 18:4 WEB

²  Jesus called a little child to himself, and set him in the midst of them,

³  and said, 'Most assuredly I tell you, unless you turn, and become as little children, you will in no way enter into the Kingdom of Heaven.

⁴  Whoever therefore humbles himself as this little child, the same is the greatest in the Kingdom of Heaven.

⁵  Whoever receives one such little child in my name receives me,

⁶  but whoever causes one of these little ones who believe in me to stumble, it would be better for him that a huge millstone should be hung around his neck, and that he should be sunk in the depths of the sea.
