'Little Children' in the Bible

At that time, Jesus answered, "I thank you, Father, Lord of heaven and earth, that you hid these things from the wise and intelligent, and revealed them to little children.

and said, "Truly I tell you, unless you turn, and become as little children, you will in no way enter into the Kingdom of Heaven.

Then little children were brought to him, that he should lay his hands on them and pray; and the disciples rebuked them.

But Jesus said, "Allow the little children, and do not forbid them to come to me; for the Kingdom of Heaven belongs to ones like these."
