Hear me, my God, as I voice my complaint; protect my life from the threat of the enemy.
…
But God will shoot them with his arrows; they will suddenly be struck down.  He will turn their own tongues against them and bring them to ruin; all who see them will shake their heads in scorn.   All people will fear; they will proclaim the works of God and ponder what he has done.  The righteous will rejoice in the Lord and take refuge in him; all the upright in heart will glory in him!

Psalm 64:1, 7-10 (NIV)
