'Strength' in the Bible

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

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

If the iron be blunt, and one do not whet the edge, then must he put to more strength: but wisdom is profitable to direct.

Happy art thou, O land, when thy king is the son of nobles, and thy princes eat in due season, for strength, and not for drunkenness!
