'Child' in the Bible

Moses gave you circumcision--not that it comes from Moses, but from the fathers--and even on the Sabbath you give a child circumcision.

If a child is given circumcision on the Sabbath so that the law of Moses may not be broken, why are you angry with me because I made a man completely well on the Sabbath?

He who is a child of God gives ear to the words of God: your ears are not open to them because you are not from God.

When a woman is about to give birth she has sorrow, because her hour is come; but when she has given birth to the child, the pain is put out of her mind by the joy that a man has come into the world.
