'Deceitful Tongue' in the Bible

Thou love all devouring words, O thou deceitful tongue.

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

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

The remnant of Israel shall not do iniquity, nor speak lies, nor shall a deceitful tongue be found in their mouth. For they shall feed and lay down, and none shall make them afraid.
