'Little Children' in the Bible

At that time Jesus said, "I praise you, Father, Lord of heaven and earth, because you have hidden these things from the wise and intelligent, and revealed them to little children.

and said, "I tell you the truth, unless you turn around and become like little children, you will never enter the kingdom of heaven!

Then little children were brought to him for him to lay his hands on them and pray. But the disciples scolded those who brought them.

But Jesus said, "Let the little children come to me and do not try to stop them, for the kingdom of heaven belongs to such as these."
