'Man of Understanding' in the Bible

It is, mere sport to a stupid man, to commit lewdness, but, wisdom, pertaineth to a man of understanding.

He that sheweth contempt for his neighbour, lacketh sense, but, a man of understanding, observeth silence.

Folly, is joy to him that lacketh sense, - but, a man of understanding, taketh a straight course.

Deep water, is counsel in a man's heart, but, a man of understanding, will draw it out.
