All the psalms show us how to pray, but in Psalm 5 David marshals his words, makes the case why God should hear him, and declares his confidence He will. He cries to the Lord to both preserve him and to destroy his enemies. Not only is this not an endorsement of personal vengeance, it’s the antidote to all ungodly violence. David commits the psalm to the chief musician leading the strings so God’s people would sing and shout with joy.
