'Age' in the Bible

Where is the wise man? Where is the scribe? Where is the debater of this age? Has not God made foolish the wisdom of the world?

Yet we do speak wisdom among those who are mature; a wisdom, however, not of this age nor of the rulers of this age, who are passing away;

the wisdom which none of the rulers of this age has understood; for if they had understood it they would not have crucified the Lord of glory;

Let no man deceive himself. If any man among you thinks that he is wise in this age, he must become foolish, so that he may become wise.

But if any man thinks that he is acting unbecomingly toward his virgin daughter, if she is past her youth, and if it must be so, let him do what he wishes, he does not sin; let her marry.
