Matthew 15:18

²⁸The heart of the righteous weighs answers, but the mouth of the wicked gushes out evil.

³⁴You offspring of vipers, how can you, being evil, speak good things? For out of the abundance of the heart, the mouth speaks.

⁶And the tongue is a fire. The world of iniquity among our members is the tongue, which defiles the whole body, and sets on fire the course of nature, and is set on fire by Gehenna.^7[+] For every kind of animal, bird, creeping thing, and sea creature is tamed, and has been tamed by mankind; ⁸but nobody can tame the tongue. It is a restless evil, full of deadly poison. ⁹With it we bless our God and Father, and with it we curse men who are made in the image of God. ¹⁰Out of the same mouth comes blessing and cursing. My brothers, these things ought not to be so.

¹¹That which enters into the mouth doesn’t defile the man; but that which proceeds out of the mouth, this defiles the man.”

²The tongue of the wise commends knowledge, but the mouths of fools gush out folly.

³²The lips of the righteous know what is acceptable, but the mouth of the wicked is perverse.

¹²A worthless person, a man of iniquity, is he who walks with a perverse mouth,

¹³As the proverb of the ancients says, ‘Out of the wicked comes wickedness;’ but my hand will not be on you.

³The words of his mouth are iniquity and deceit. He has ceased to be wise and to do good.

²²“He said to him, ‘Out of your own mouth I will judge you, you wicked servant! You knew that I am an exacting man, taking up that which I didn’t lay down and reaping that which I didn’t sow.
