'Little Child' in the Bible

And he took a little child, and put him in the midst of them. And taking him in his arms, he said to them,

"Whoever receives one of these little children in my name receives me; and whoever receives me, receives not me but him who sent me."

But when Jesus saw it, he was indignant and said to them, "Let the little children come to me; and do not hinder them, for to such belongs the kingdom of God.

Truly, I say to you, whoever does not receive the kingdom of God like a little child will not enter it."
