'Profitable' in the Bible

"Is it to God that a strong man is of benefit? Is it to him that even a wise man is profitable?

For her benefit is more profitable than silver, and her gain is better than gold.

I thought deeply about the effects of indulging myself with wine (all the while my mind was guiding me with wisdom) and the effects of behaving foolishly, so that I might discover what is profitable for people to do on earth during the few days of their lives.

It is necessary to go on boasting. Though it is not profitable, I will go on to visions and revelations from the Lord.
