Matthew Poole and continuators on Proverbs 10:9

9. He that walketh uprightly , walketh surely : but he that perverteth his ways shall be known .

Who is sincere, and just, and faithful in his dealings with God and with men.

Or, securely, or confidently, as the word properly signifies, and is here rendred by all the ancient Interpreters, and by most of the others, quietly resting upon Gods Favour, and gracious Providence for his Protection, and being supported by the Testimony of a good Conscience, and therefore not fearing nor caring who knows or observes his Actions, which he endeavours to approve both to God, and to men.

That walks perversly, or frowardly, or in crooked and sinful paths, that dealeth hypocritically and deceitfully with God, or with men, using all possible crafts to conceal his wickedness.

His wickedness shall be publickly discovered, and so he shall be exposed to all that shame and punishment which his sins deserve, and which he thought by his cunning practices to avoid.
