He delivered me from my strong enemy - The enemy that had more power than I had, and that was likely to overcome me. It is probable that the allusion here in the mind of the psalmist would be particularly to Saul.
And from them which hated me - From all who hated and persecuted me, in the time of Saul, and ever onward during my life.
For they were too strong for me - I had no power to resist them, and when I was about to sink under their opposition and malice, God interposed and rescued me. David, valiant and bold as he was as a warrior, was not ashamed, in the review of his life, to admit that he owed his preservation not to his own courage and skill in war, but to God; that his enemies were superior to himself in power; and that if God had not interposed he would have been crushed and destroyed. No man dishonors himself by acknowledging that he owes his success in the world to the divine interposition.
