(Luke 6:45) 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.
(Mark 7:21, 22) For from within, out of the heart of men, proceed evil thoughts, adulteries, fornications, murders, Thefts, covetousness, wickedness, deceit, lasciviousness, an evil eye, blasphemy, pride, foolishness:
(Proverbs 4:23-27) Keep thy heart with all diligence; for out of it [are] the issues of life. Put away from thee a froward mouth, and perverse lips put far from thee. Let thine eyes look right on, and let thine eyelids look straight before thee. Ponder the path of thy feet, and let all thy ways be established. Turn not to the right hand nor to the left: remove thy foot from evil.
(Proverbs 16:27-31) An ungodly man diggeth up evil: and in his lips [there is] as a burning fire. A froward man soweth strife: and a whisperer separateth chief friends. A violent man enticeth his neighbour, and leadeth him into the way [that is] not good. He shutteth his eyes to devise froward things: moving his lips he bringeth evil to pass. The hoary head [is] a crown of glory, [if] it be found in the way of righteousness.
(Proverbs 16:16, 17) How much better [is it] to get wisdom than gold! and to get understanding rather to be chosen than silver! The highway of the upright [is] to depart from evil: he that keepeth his way preserveth his soul.
(Proverbs 11:2-8) [When] pride cometh, then cometh shame: but with the lowly [is] wisdom. The integrity of the upright shall guide them: but the perverseness of transgressors shall destroy them. Riches profit not in the day of wrath: but righteousness delivereth from death. The righteousness of the perfect shall direct his way: but the wicked shall fall by his own wickedness. The righteousness of the upright shall deliver them: but transgressors shall be taken in [their own] naughtiness. When a wicked man dieth, [his] expectation shall perish: and the hope of unjust [men] perisheth. The righteous is delivered out of trouble, and the wicked cometh in his stead.
(Proverbs 13:6-11) Righteousness keepeth [him that is] upright in the way: but wickedness overthroweth the sinner. There is that maketh himself rich, yet [hath] nothing: [there is] that maketh himself poor, yet [hath] great riches. The ransom of a man’s life [are] his riches: but the poor heareth not rebuke. The light of the righteous rejoiceth: but the lamp of the wicked shall be put out. Only by pride cometh contention: but with the well advised [is] wisdom. Wealth [gotten] by vanity shall be diminished: but he that gathereth by labour shall increase.
