Proverbs 24:9

For out of the heart proceed evil thoughts, murders, adulteries, fornications, thefts, false witness, blasphemies:

Casting down imaginations, and every high thing that exalteth itself against the knowledge of God, and bringing into captivity every thought to the obedience of Christ;

Let the wicked forsake his way, and the unrighteous man his thoughts: and let him return unto the LORD, and he will have mercy upon him; and to our God, for he will abundantly pardon.

Repent therefore of this thy wickedness, and pray God, if perhaps the thought of thine heart may be forgiven thee.

Scornful men bring a city into a snare: but wise men turn away wrath.

He that deviseth to do evil shall be called a mischievous person.

And Jesus knowing their thoughts said, Wherefore think ye evil in your hearts?

And God saw that the wickedness of man was great in the earth, and that every imagination of the thoughts of his heart was only evil continually.

But I say unto you, That whosoever looketh on a woman to lust after her hath committed adultery with her already in his heart.

O Jerusalem, wash thine heart from wickedness, that thou mayest be saved. How long shall thy vain thoughts lodge within thee?

Cast out the scorner, and contention shall go out; yea, strife and reproach shall cease.

For as he thinketh in his heart, so is he: Eat and drink, saith he to thee; but his heart is not with thee.

I hate vain thoughts: but thy law do I love.

And the LORD smelled a sweet savour; and the LORD said in his heart, I will not again curse the ground any more for man’s sake; for the imagination of man’s heart is evil from his youth; neither will I again smite any more every thing living, as I have done.
