20 He that hath a froward  heart findeth no good: and he that hath a perverse tongue falleth into mischief.
20 One whose heart is corrupt does not prosper; one whose tongue is perverse falls into trouble.
20 A man of crooked heart does not discover good, and one with a dishonest tongue falls into calamity.
20 A bad motive can't achieve a good end; double-talk brings you double trouble.
20 He who has a deceitful heart finds no good, And he who has a perverse tongue falls into evil.
20 The crooked heart will not prosper; the lying tongue tumbles into trouble.

There is nothing got by ill designs. And many have paid dear for an unbridled tongue.
