Psalms 64:3

⁴My soul is among lions. I lie among those who are set on fire, even the sons of men, whose teeth are spears and arrows, and their tongue a sharp sword.

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.

⁷Let them vanish like water that flows away. When they draw the bow, let their arrows be made blunt.

²For, behold, the wicked bend their bows. They set their arrows on the strings, that they may shoot in darkness at the upright in heart.

³“They bend their tongue, as their bow, for falsehood. They have grown strong in the land, but not for truth; for they proceed from evil to evil, and they don’t know me,” says the LORD.

¹⁸There is one who speaks rashly like the piercing of a sword, but the tongue of the wise heals.

¹⁷No weapon that is formed against you will prevail; and you will condemn every tongue that rises against you in judgment. This is the heritage of the LORD’s servants, and their righteousness is of me,” says the LORD.

¹⁴There is a generation whose teeth are like swords, and their jaws like knives, to devour the poor from the earth, and the needy from among men.
