'Boy' in the Bible

“Sir,” the official said to Him, “come down before my boy dies!”

While he was still going down, his slaves met him saying that his boy was alive.

“There’s a boy here who has five barley loaves and two fish—but what are they for so many?”

Moses has given you circumcision (not that it is of Moses, but of the fathers), and on the Sabbath you circumcise a boy.

If a boy receives circumcision on the Sabbath, that the law of Moses may not be broken, are you angry with me, because I made a man completely healthy on the Sabbath?
