⁴⁵ 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.

³⁴ O generation of vipers, how can ye, being evil, speak good things? for out of the abundance of the heart the mouth speaketh.

³⁵ 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.

²¹ For from within, out of the heart of men, proceed evil thoughts, adulteries, fornications, murders,

²² Thefts, covetousness, wickedness, deceit, lasciviousness, an evil eye, blasphemy, pride, foolishness:

²³ All these evil things come from within, and defile the man.

²³ Search me, O God, and know my heart: try me, and know my thoughts:

²⁴ And see if there be any wicked way in me, and lead me in the way everlasting.

⁹ The heart is deceitful above all things, and desperately wicked: who can know it?

¹⁹ For out of the heart proceed evil thoughts, murders, adulteries, fornications, thefts, false witness, blasphemies:

¹⁹ Hear thou, my son, and be wise, and guide thine heart in the way.

²⁶ He that trusteth in his own heart is a fool: but whoso walketh wisely, he shall be delivered.
