Proverbs 17:27

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

He who spares his words has knowledge. He who is even tempered is a man of understanding.

He that spareth his words hath knowledge; And he that is of a cool spirit is a man of understanding.

One acquainted with knowledge is sparing his words, And the cool of temper `is' a man of understanding.

A man of knowledge restrains his words, and a man of understanding maintains a calm spirit.
