'Tongue' in the Bible

And they bend their tongue, as it were their bow, for falsehood; and they are grown strong in the land, but not for truth: for they proceed from evil to evil, and they know not me, saith Jehovah.

And they will deceive every one his neighbor, and will not speak the truth: they have taught their tongue to speak lies; they weary themselves to commit iniquity.

Their tongue is a deadly arrow; it speaketh deceit: one speaketh peaceably to his neighbor with his mouth, but in his heart he layeth wait for him.

Then said they, Come, and let us devise devices against Jeremiah; for the law shall not perish from the priest, nor counsel from the wise, nor the word from the prophet. Come, and let us smite him with the tongue, and let us not give heed to any of his words.
