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.

O generation of vipers, how can ye, being evil, speak good things? for out of the abundance of the heart the mouth speaketh. A good man out of the good treasure of the heart bringeth forth good things: and an evil man out of the evil treasure bringeth forth evil things.

Thefts, covetousness, wickedness, deceit, lasciviousness, an evil eye, blasphemy, pride, foolishness: covetousness...: Gr. covetousnesses, wickednesses All these evil things come from within, and defile the man. And from thence he arose, and went into the borders of Tyre and Sidon, and entered into an house, and would have no man know it: but he could not be hid.

Search me, O God, and know my heart: try me, and know my thoughts: And see if there be any wicked way in me, and lead me in the way everlasting. wicked...: Heb. way of pain, or, grief

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

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

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.

But every man is tempted, when he is drawn away of his own lust, and enticed. Then when lust hath conceived, it bringeth forth sin: and sin, when it is finished, bringeth forth death.

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;
