'Young' in the Bible

So his servants said to him, Let search be made for a young virgin for my lord the king, to take care of him and be waiting on him; and you may take her in your arms, and so my lord the king will be warm.

So after searching through all the land of Israel for a fair young girl, they saw Abishag the Shunammite, and took her to the king.

And now, O Lord my God, you have made your servant king in the place of David my father; and I am only a young boy, with no knowledge of how to go out or come in.

Hadad, being still a young boy, went in flight to Egypt, with certain Edomites, servants of his father;

But he gave no attention to the opinion of the old men, and went to the young men of his generation who were waiting before him:

And the young men of his generation said to him, This is the answer to give to the people who came to you saying, Your father put a hard yoke on us; will you make it less? say to them, My little finger is thicker than my father's body;

But giving them the answer put forward by the young men, saying, My father made your yoke hard, but I will make it harder; my father gave you punishment with whips, but I will give it with snakes.
