'Man of Understanding' in the Bible

Also Jonathan, David’s uncle, was a counselor, a man of understanding, and a scribe; and Jehiel the son of Hachmoni tutored the king’s sons.

A wise man will hear and increase in learning,And a man of understanding will acquire wise counsel,

Doing wickedness is like sport to a fool,And so is wisdom to a man of understanding.

He who despises his neighbor lacks sense,But a man of understanding keeps silent.

Folly is joy to him who lacks sense,But a man of understanding walks straight.

He who restrains his words has knowledge,And he who has a cool spirit is a man of understanding.

A plan in the heart of a man is like deep water,But a man of understanding draws it out.

By the transgression of a land many are its princes,But by a man of understanding and knowledge, so it endures.
