'Little Children' in the Bible

Whosoever shall receive one of such little children in my name, receives me; and whosoever shall receive me, does not receive me, but him who sent me.

And they brought little children to him that he might touch them. But the disciples rebuked those that brought them.

But Jesus seeing it, was indignant, and said to them, Suffer the little children to come to me; forbid them not; for of such is the kingdom of God.
