'Strength' in the Bible

Wisdom is a strength to the wise man more than ten rulers who are in a city.

Then I said, "Wisdom is better than strength." Nevertheless the poor man's wisdom is despised, and his words are not heard.

If the axe is blunt, and one doesn't sharpen the edge, then he must use more strength; but skill brings success.

Happy are you, land, when your king is the son of nobles, and your princes eat in due season, for strength, and not for drunkenness!
