Proverbs 17:20

and the hard-hearted man comes not in for good. A man of a changeful tongue will fall into mischiefs;

and the hard-hearted man comes not in for good. A man of a changeful tongue will fall into mischiefs;

He that hath a froward heart findeth no good: and he that hath a perverse tongue falleth into mischief.

One who has a perverse heart doesn’t find prosperity, and one who has a deceitful tongue falls into trouble.
