'Little Child' in the Bible

Whosoever shall receive one of such little children in my name, receiveth me: and whosoever receiveth me, receiveth not me merely, but him that sent me.

And they brought unto him little children, that he should touch them: but his disciples rebuked those who brought them.

But when Jesus saw it, he felt indignation, and said to them, Permit little children to come to me, and hinder them not; for of such is the kingdom of heaven.

Verily I say unto you, Whosoever shall not receive the kingdom of God as a little child, he shall in nowise enter into it.
