Proverbs 6:12

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

²⁴Put away from yourself a perverse mouth. Put corrupt lips far from you.

²⁷A worthless man devises mischief. His speech is like a scorching fire.

¹³Besides, they also learn to be idle, going about from house to house. Not only idle, but also gossips and busybodies, saying things which they ought not.

⁷Behold, they spew with their mouth. Swords are in their lips, “For”, they say, “who hears us?”

²Your tongue plots destruction, like a sharp razor, working deceitfully. ³You love evil more than good, lying rather than speaking the truth. Selah. ⁴You love all devouring words, you deceitful tongue.

¹⁰For there are also many unruly men, vain talkers and deceivers, especially those of the circumcision, ¹¹whose mouths must be stopped: men who overthrow whole houses, teaching things which they ought not, for dishonest gain’s sake.

¹³The fear of the LORD is to hate evil. I hate pride, arrogance, the evil way, and the perverse mouth.

³⁰Men will arise from among your own selves, speaking perverse things, to draw away the disciples after them.

⁴An evildoer heeds wicked lips. A liar gives ear to a mischievous tongue.
