'Man of Understanding' in the Bible

And, Jonathan the relative of David, was a counsellor, a man of understanding and a scribe, was he. And, Jehiel son of Hachmoni, was with the sons of the king.

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.
