'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.

For the wisdom of this age is foolishness with God. As it is written, "He catches the wise in their craftiness."

But if any man think that he behaveth himself uncomely toward his virgin, if she pass the flower of her age, and need so require, let him do what he will, he sinneth not: let them marry.

wherefore, if victuals cause my brother to stumble, I may eat no flesh -- to the age -- that my brother I may not cause to stumble.
