Psalms 18:46-50 (Spurgeon's Abridged Commentary).

The Lord lives, and blessed be my rock, and exalted be the God of my salvation -

the God who gave me vengeance and subdued peoples under me,

Who rescued me from my enemies; yes you exalted me above those who rose against me; you delivered me from the man of violence.

For this I will praise you, O LORD, among the nations, and sing to your name.

Great salvation he brings to his king, and shows steadfast love to his anointed, to David and his offspring forever.
