Romans 3:13

For there is no faithfulness in their mouth; their inward part is very wickedness; their throat is an open sepulchre; they flatter with their tongue.

They have sharpened their tongues like a serpent; adders’ poison is under their lips. Selah.

Woe unto you, scribes and Pharisees, hypocrites! for ye are like unto whited sepulchres, which indeed appear beautiful outward, but are within full of dead men’s bones, and of all uncleanness. Even so ye also outwardly appear righteous unto men, but within ye are full of hypocrisy and iniquity.

And they bend their tongues like their bow for lies: but they are not valiant for the truth upon the earth; for they proceed from evil to evil, and they know not me, saith the Lord. Take ye heed every one of his neighbour, and trust ye not in any brother: for every brother will utterly supplant, and every neighbour will walk with slanders. And they will deceive every one his neighbour, and will not speak the truth: they have taught their tongue to speak lies, and weary themselves to commit iniquity.

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

Have ye not seen a vain vision, and have ye not spoken a lying divination, whereas ye say, The Lord saith it; albeit I have not spoken?

For your hands are defiled with blood, and your fingers with iniquity; your lips have spoken lies, your tongue hath muttered perverseness.

Even so the tongue is a little member, and boasteth great things. Behold, how great a matter a little fire kindleth! And 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. For every kind of beasts, and of birds, and of serpents, and of things in the sea, is tamed, and hath been tamed of mankind: But the tongue can no man tame; it is an unruly evil, full of deadly poison.

O generation of vipers, how can ye, being evil, speak good things? for out of the abundance of the heart the mouth speaketh. A good man out of the good treasure of the heart bringeth forth good things: and an evil man out of the evil treasure bringeth forth evil things.

Thy tongue deviseth mischiefs; like a sharp razor, working deceitfully.

Their quiver is as an open sepulchre, they are all mighty men.

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

God forbid: yea, let God be true, but every man a liar; as it is written, That thou mightest be justified in thy sayings, and mightest overcome when thou art judged.

Their wine is the poison of dragons, and the cruel venom of asps.

The Lord shall cut off all flattering lips, and the tongue that speaketh proud things: Who have said, With our tongue will we prevail; our lips are our own: who is lord over us?

Yet his meat in his bowels is turned, it is the gall of asps within him. He hath swallowed down riches, and he shall vomit them up again: God shall cast them out of his belly. He shall suck the poison of asps: the viper’s tongue shall slay him.
