Psalms 31:21

Blessed be the Lord Cp. Psalms 28:6.

he hath shewed me his marvellous kindness Lit. he hath made marvellous his lovingkindness to me, as in Psalms 17:7.

in a strong city Either, as in a strong city, putting me out of the reach of my enemies as it were in a fortified city; or, as a strong city,proving Himself my fortress (Psalms 31:2). The words may also mean in a besieged city, which might be taken as a metaphor for trouble generally. Some commentators understand the words literally of David's escape from Keilah, or of his establishment in Ziklag; or of Jeremiah in Jerusalem during the siege.
