Psalms 64:6

6They search out injustice,
saying, “We have accomplished a diligent search.”
For athe inward mind and heart of a man are deep.

Jeremiah 9:8

8 bTheir tongue is a deadly arrow;
cit speaks deceitfully;
with his mouth deach speaks peace to his neighbor,
but in his heart ehe plans an ambush for him.
