Psalms 64:3-4, 8
Psalms 64:3-4 NASB1995
Who have sharpened their tongue like a sword. They aimed bitter speech as their arrow, To shoot from concealment at the blameless; Suddenly they shoot at him, and do not fear.
Psalms 64:8 NASB1995
So they will make him stumble; Their own tongue is against them; All who see them will shake the head.
