'Powerful' in the Bible

I looked again, and I saw all the oppression that occurs under the sun. {I saw the tears of the oppressed-- no one comforts them! Those who oppress them are powerful-- no one can comfort them}!

Whatever exists has been named already; people know what it means to be human and a person cannot defeat one who is more powerful than he.

Wisdom given as strength to a wise person is better than having ten powerful men in the city.

Since a king's command is powerful, who is able to challenge him, asking, "What are you doing?"
