For the choirmaster. Of David the servant of the LORD, who sang this song to the LORD on the day the LORD had delivered him from the hand of all his enemies and from the hand of Saul. He said:
Thou wentest forth for the salvation of thy people, even for salvation with thine anointed; thou woundedst the head out of the house of the wicked, by discovering the foundation unto the neck. Selah.
