Psalms
Behold, he travaileth with iniquity, and hath conceived mischief, and brought forth falsehood.
He made a pit, and digged it, and is fallen into the ditch which he made.
His mischief shall return upon his own head, and his violent dealing shall come down upon his own pate.
Proverbs
Put away from thee a froward mouth, and perverse lips put far from thee.
Isaiah
The instruments also of the churl are evil: he deviseth wicked devices to destroy the poor with lying words, even when the needy speaketh right.
1 Corinthians
Be not deceived: evil communications corrupt good manners.
