Proverbs 4:23

A good man out of the good treasure of his heart bringeth forth that which is good; and an evil man out of the evil treasure of his heart bringeth forth that which is evil: for of the abundance of the heart his mouth speaketh.

He that keepeth his mouth keepeth his life: but he that openeth wide his lips shall have destruction.

The heart is deceitful above all things, and desperately wicked: who can know it?

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

Hear thou, my son, and be wise, and guide thine heart in the way.

He that trusteth in his own heart is a fool: but whoso walketh wisely, he shall be delivered.

Watch ye and pray, lest ye enter into temptation. The spirit truly is ready, but the flesh is weak.

Only take heed to thyself, and keep thy soul diligently, lest thou forget the things which thine eyes have seen, and lest they depart from thy heart all the days of thy life: but teach them thy sons, and thy sons’ sons;

Looking diligently lest any man fail of the grace of God; lest any root of bitterness springing up trouble you, and thereby many be defiled;

Wisdom is the principal thing; therefore get wisdom: and with all thy getting get understanding.

My son, let not them depart from thine eyes: keep sound wisdom and discretion:

Thorns and snares are in the way of the froward: he that doth keep his soul shall be far from them.

A gracious woman retaineth honour: and strong men retain riches.

There is a sore evil which I have seen under the sun, namely, riches kept for the owners thereof to their hurt.
