'Little Child' in the Bible

Jesus, perceiving the thought of their heart, took a little child and set him by him,

and said to them, "Whoever receives this little child in my name receives me, and whoever receives me receives him who sent me. For he who is least among you all is the one who is great."

But Jesus called them to him and said, "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."
