Matthew Poole and continuators on Proverbs 22:20

20 Have not I written to thee excellent things in counsels and knowledg :

Or, princely things, as they are called, Prov. 8. 6. the great things of Gods law, as Hos. 8▪ 12.

Consisting of Counsels to direct thy practice, and Knowledg to inform and enrich thy mind. Or, by that known Figure Hendiadis, in counsels of knowledg, i. e. in good counsels which proceed from sound knowledge, and make a man knowing and wise, which are opposed to the counsels of the wicked, Prov. 12. 5. which are without knowledg.

Marginal references: Heb. things of command or authority.
