Psalms 64:3-6 New King James Version (NKJV)

3. Who sharpen their tongue like a sword,And bend their bows to shoot their arrows—bitter words,

4. That they may shoot in secret at the blameless;Suddenly they shoot at him and do not fear.

5. They encourage themselves in an evil matter;They talk of laying snares secretly;They say, “Who will see them?”

6. They devise iniquities:“We have perfected a shrewd scheme.”Both the inward thought and the heart of man are deep.
