'Man of Understanding' in the Bible

A wise man will hear, and will increase learning; and a man of understanding shall attain unto wise counsels:

It is as sport to a fool to do wrong: but a man of understanding has wisdom.

He that is void of wisdom despises his neighbor: but a man of understanding holds his peace.

Folly is joy to him that is destitute of wisdom: but a man of understanding walks uprightly.

He that has knowledge spares his words: and a man of understanding is of an excellent spirit.

Even a fool, when he holds his peace, is counted wise: and he that shuts his lips is esteemed a man of understanding.

Counsel in the heart of man is like deep water; but a man of understanding will draw it out.

For the transgression of a land many are the princes thereof: but by a man of understanding and knowledge its state shall be prolonged.
