'Deceitful Lips' in the Bible

The LORD shall root out all deceitful lips, and the tongue that speaketh proud things,

O Yahweh, hear a just cause. Hear my cry; heed my prayer [I make] without deceitful lips.

The LORD abhoreth deceitful lips; but they that labour for truth please him.

Better a poor man who lives with integritythan someone who has deceitful lips and is a fool.
