'Boy' in the Bible

And Jesus rebuked him, and the demon went out from him, and the boy was healed from that hour.

and had completed the days, as they returned, the boy Jesus remained behind in Jerusalem, and his parents knew not of it;

There is a little boy here who has five barley loaves and two small fishes; but this, what is it for so many?

And they brought away the boy alive, and were no little comforted.
