Psalms 31:21

Blessed be the Lord,....

Faith and prayer must go together. He that believes, let his pray-- I believe, therefore I have spoken: and he that prays, let him believe, for the prayer of faith is the prevailing prayer. David, in distress, is very earnest with God in prayer for succour and relief.

Blessed be the Lord. When the Lord blesses us we cannot do less than bless him in return. For he hath shewed me his marvellous kindness in a strong city. Was this in Mahanaim, where the Lord gave him victory over the hosts of Absalom? Or did he refer to Rabbath of Ammon, where he gained signal triumphs? Or, best of all, was Jerusalem the strong city where he most experienced the astonishing kindness of his God? Gratitude is never short of subjects; her Ebenezers stand so close together as to wall up her path to heaven on both sides.

Whether in cities or in hamlets our blessed Lord has revealed himself to us, we shall never forget the hallowed spots: the lonely mount of Hermon, or the village of Emmaus, or the rock of Patmos, or the wilderness of Horeb, are all alike renowned when God manifests himself to us in robes of love.

Being full of faith, the psalmist gives glory to God for the mercy which he is assured will be his position.

In a strong city - If this Psalm was written by David, this must refer to his taking refuge with achish, king of Gath, who gave him Ziklag, a fortified city, to secure himself and followers in. See 1Sa 27:6. This is more likely than that it was Keilah, where he only had intimation of the traitorous design of the inhabitants to deliver him up to Saul; so that the place was no refuge to him, howsoever fortified. Perhaps the passage may mean that, under the protection of God, he was as safe as if he had been in a fortified city.

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” 1Sa 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.
