To the choirmaster. A Psalm of David the servant of the LORD, who addressed the words of this song to the LORD on the day when the LORD delivered him from the hand of all his enemies, and from the hand of Saul. He said: I love thee, O LORD, my strength. The LORD is my rock, and my fortress, and my deliverer, my God, my rock, in whom I take refuge, my shield, and the horn of my salvation, my stronghold. I call upon the LORD, who is worthy to be praised, and I am saved from my enemies.
–Psalm 18:1-3
