To the leader. A Pslam of David

Hear my voice, O God, in my 
complaint;
preserve my life from the dread
enemy.
Hide me from the secret plots of the 
wicked,
from the scheming of evildoers,
who whet their tongues like swords,
who aim bitter words like arrows,
shooting from ambush at the 
blameless;
they shoot suddenly and without 
fear.
They hold fast to their evil purpose;
they talk of laying snares secretly,
thinking, 'who can see us?
Who can search out our crimes?
We have thought out a cunningly
conceived plot.'
For the human heart and mind are 
deep.

But God will shoot his arrow at them;
they will be wounded suddenly.
Because of their tongue he will bring
them to ruin;
all who see them will shake with
horror.
Then everyone will fear;
they will tell what God has
brought about,
and ponder what he has done.

Let the righteous rejoice in the LORD
and take refuge in him.
Let all the upright in heart glory. (Psalm 64:1-10)
