'Deceitful Tongue' in the Bible

Deliver my soul, O LORD, from lying lips, and from a deceitful tongue!

A wicked body giveth audience to false lips; and a dissembling person giveth ear to a deceitful tongue.

among those that be full of riches unrighteously gotten: where the citizens deal with falsity, speak lies, and have deceitful tongues in their mouths?

The remnant of Israel shall do no wickedness, nor speak lies: neither shall there any deceitful tongue be found in their mouths. For they shall be fed, and take their rest, and no man shall make them afraid.
