Psalm 64 (KJV)

1 Hear my voice, O God, in my prayer: preserve my life from fear of the enemy.
5 They encourage themselves in an evil matter: they commune of laying snares (traps, nets) privily (secret); they say, Who shall see them?
6 They search out iniquities (wickedness); they accomplish a diligent search: both the inward thought of every one of them, and the heart, is deep.
