'Little Children' in the Bible

But to what shall I compare the present generation? It is like little children sitting in the market-places and calling out to their playmates--

"I tell you, unless you change and become like little children, you will not enter the Kingdom of Heaven at all.

Then some little children were brought to Jesus, for him to place his hands on them, and pray; but the disciples found fault with those who had brought them.

Jesus, however, said: "Let the little children come to me, and do not hinder them, for it is to the childlike that the Kingdom of Heaven belongs."
