'Age' in the Bible

and the commander of the officials said to Daniel, “I am afraid of my lord the king, who has prearranged your food and your drink; for why should he see your faces looking more haggard than the young men who are your own age? Then you would make me forfeit my head to the king.”

But as for you (Daniel), go your way until the end [of your life]; for you will rest and rise again for your allotted inheritance at the end of the age.”
