'Deceitful Tongue' in the Bible

You love all devouring words, O deceitful tongue,

"Deliver my life, O Yahweh, from lying lips, from a deceitful tongue."

What shall be given to you, and what more shall be done to you, deceitful tongue?

The remnant of Israel shall not do wickedness; they shall not speak deception, nor shall a deceitful tongue be found in their mouth. For they shall graze and lie down, and none shall frighten [them]."
