Proverbs 11:15

¹³ A talebearer revealeth secrets: but he that is of a faithful spirit concealeth the matter.

¹⁴ Where no counsel is, the people fall: but in the multitude of counsellors there is safety.

He that is surety for a stranger shall smart for it: and he that hateth suretiship is sure.

¹⁶ A gracious woman retaineth honour: and strong men retain riches.

¹⁷ The merciful man doeth good to his own soul: but he that is cruel troubleth his own flesh.
