Matthew 15:18–19

²⁸The heart of the righteous studieth to answer: but the mouth of the wicked poureth out evil things.

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

⁶And the tongue is a fire, a world of iniquity: so is the tongue among our members, that it defileth the whole body, and setteth on fire the course of nature; and it is set on fire of hell.

⁷For every kind of beasts, and of birds, and of serpents, and of things in the sea, is tamed, and hath been tamed of mankind:

⁸But the tongue can no man tame; it is an unruly evil, full of deadly poison.

⁹Therewith bless we God, even the Father; and therewith curse we men, which are made after the similitude of God.

¹⁰Out of the same mouth proceedeth blessing and cursing. My brethren, these things ought not so to be.

¹¹Not that which goeth into the mouth defileth a man; but that which cometh out of the mouth, this defileth a man.

³²The lips of the righteous know what is acceptable: but the mouth of the wicked speaketh frowardness.

²The tongue of the wise useth knowledge aright: but the mouth of fools poureth out foolishness.

¹²¶ A naughty person, a wicked man, walketh with a froward mouth.

¹³As saith the proverb of the ancients, Wickedness proceedeth from the wicked: but mine hand shall not be upon thee.

²²And he saith unto him, Out of thine own mouth will I judge thee, thou wicked servant. Thou knewest that I was an austere man, taking up that I laid not down, and reaping that I did not sow:

³The words of his mouth are iniquity and deceit: he hath left off to be wise, and to do good.

⁵And there was given unto him a mouth speaking great things and blasphemies; and power was given unto him to continue forty and two months.

⁶And he opened his mouth in blasphemy against God, to blaspheme his name, and his tabernacle, and them that dwell in heaven.

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

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

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

¹⁹Now the works of the flesh are manifest, which are these; Adultery, fornication, uncleanness, lasciviousness,

²⁰Idolatry, witchcraft, hatred, variance, emulations, wrath, strife, seditions, heresies,

²¹Envyings, murders, drunkenness, revellings, and such like: of the which I tell you before, as I have also told you in time past, that they which do such things shall not inherit the kingdom of God.

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

¹³Let no man say when he is tempted, I am tempted of God: for God cannot be tempted with evil, neither tempteth he any man:

¹⁴But every man is tempted, when he is drawn away of his own lust, and enticed.

¹⁵Then when lust hath conceived, it bringeth forth sin: and sin, when it is finished, bringeth forth death.

²To speak evil of no man, to be no brawlers, but gentle, shewing all meekness unto all men.

³For we ourselves also were sometimes foolish, disobedient, deceived, serving divers lusts and pleasures, living in malice and envy, hateful, and hating one another.

⁴But after that the kindness and love of God our Saviour toward man appeared,

⁵Not by works of righteousness which we have done, but according to his mercy he saved us, by the washing of regeneration, and renewing of the Holy Ghost;

⁶Which he shed on us abundantly through Jesus Christ our Saviour;

²³¶ Keep thy heart with all diligence; for out of it are the issues of life.

⁵¶ 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.

¹⁴O Jerusalem, wash thine heart from wickedness, that thou mayest be saved. How long shall thy vain thoughts lodge within thee?

¹⁰As it is written, There is none righteous, no, not one:

¹¹There is none that understandeth, there is none that seeketh after God.

¹²They are all gone out of the way, they are together become unprofitable; there is none that doeth good, no, not one.

¹³Their throat is an open sepulchre; with their tongues they have used deceit; the poison of asps is under their lips:

¹⁴Whose mouth is full of cursing and bitterness:

¹⁵Their feet are swift to shed blood:

¹⁶Destruction and misery are in their ways:

¹⁷And the way of peace have they not known:

¹⁸There is no fear of God before their eyes.

¹⁹Now we know that what things soever the law saith, it saith to them who are under the law: that every mouth may be stopped, and all the world may become guilty before God.

²²Repent therefore of this thy wickedness, and pray God, if perhaps the thought of thine heart may be forgiven thee.

⁷Let 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.

⁷Their feet run to evil, and they make haste to shed innocent blood: their thoughts are thoughts of iniquity; wasting and destruction are in their paths.

¹⁴Frowardness is in his heart, he deviseth mischief continually; he soweth discord.

¹¹³I hate vain thoughts: but thy law do I love.

¹AND you hath he quickened, who were dead in trespasses and sins;

²Wherein in time past ye walked according to the course of this world, according to the prince of the power of the air, the spirit that now worketh in the children of disobedience:

³Among whom also we all had our conversation in times past in the lusts of our flesh, fulfilling the desires of the flesh and of the mind; and were by nature the children of wrath, even as others.

²¹And 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.

⁴And Jesus knowing their thoughts said, Wherefore think ye evil in your hearts?

¹⁸For I know that in me (that is, in my flesh,) dwelleth no good thing: for to will is present with me; but how to perform that which is good I find not.

⁹The thought of foolishness is sin: and the scorner is an abomination to men.

¹⁵Foolishness is bound in the heart of a child; but the rod of correction shall drive it far from him.

⁷Because the carnal mind is enmity against God: for it is not subject to the law of God, neither indeed can be.

⁸So then they that are in the flesh cannot please God.
