'Wise' in the Bible

That old men are to be simple in their tastes, serious, wise, true in faith, in love, and of a quiet mind.

To be wise in mind, clean in heart, kind; working in their houses, living under the authority of their husbands; so that no evil may be said of the word of God.

To the young men give orders to be wise and serious-minded:

sound and beyond reproach in instruction, so that the opponent [of the faith] will be shamed, having nothing bad to say about us.
