Thou lovest all devouring words, O thou deceitful tongue.

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

What shall be given unto thee, and what shall be done more unto thee, Thou deceitful tongue?

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

One who has a perverse heart doesn't find prosperity, and one who has a deceitful tongue falls into trouble.

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 not do iniquity, nor speak lies; neither shall a deceitful tongue be found in their mouth: for they shall feed and lie down, and none shall make them afraid.
