Proverbs 11:17

15 He who puts up security for a stranger will surely suffer, but the one who hates indebtedness is secure.

16 A gracious woman attains honor, but ruthless men gain only wealth.

A kind man benefits himself, but a cruel man brings trouble on himself.

18 The wicked man earns an empty wage, but he who sows righteousness reaps a true reward.

19 Genuine righteousness leads to life, but the pursuit of evil brings death.

Do read the surrounding verses too, because the context often says more than a single verse.
