'Age' in the Bible

Where is the philosopher? Where is the scholar? Where is the debater of this age? Hasn’t God made the world’s wisdom foolish?

However, we do speak a wisdom among the mature, but not a wisdom of this age, or of the rulers of this age, who are coming to nothing.

None of the rulers of this age knew this wisdom, for if they had known it, they would not have crucified the Lord of glory.

No one should deceive himself. If anyone among you thinks he is wise in this age, he must become foolish so that he can become wise.

But if any man thinks he is acting improperly toward his virgin, if she is past marriageable age, and so it must be, he can do what he wants. He is not sinning; they can get married.
