Blessed be the Lord - An expression of thanksgiving for the evidence that God had heard him in his troubles, and had answered him.
For he hath showed me his marvelous kindness - literally, “He has made his mercy wonderful;” that is, he has showed me such mercy as to be an object of admiration and astonishment. It was not ordinary kindness, such as is shown to people every day; it was so uncommon - so far beyond all expectation - so separate from second causes and the agency of man - so marked in its character - as to fill the mind with wonder.
In a strong city - Margin, “fenced city.” This may mean either that he had thus placed him literally in a strongly fortified city where he was safe from the fear of his enemies; or, that he had interposed in his behalf, and had given him protection as if he had brought him into such a strongly fortified place. Jarchi supposes that the city of “Keilah” 1 Samuel 23:7 is here intended. But this is improbable. All that the passage necessarily implies is, that God had given him protection as if he had been placed in a strongly fortified town where he would be safe from danger.
