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:
But thus saith the Lord, Even the captives of the mighty shall be taken away, and the prey of the terrible shall be delivered: for I will contend with him that contendeth with thee, and I will save thy children.
