'Character' in the Bible

And I set my mind to know [practical] wisdom and to discern [the character of] madness and folly [in which men seem to find satisfaction]; I realized that this too is a futile grasping and chasing after the wind.

Blessed [prosperous and admired] are you, O land, when your king is a man of noble birth, and your princes and officials feast at the proper time—for strength and not for drunkenness.

When all has been heard, the end of the matter is: fear God [worship Him with awe-filled reverence, knowing that He is almighty God] and keep His commandments, for this applies to every person.
