Psalms 59:17

Unto Thee, O my Strength, by whose mighty power he had been delivered, will I sing, with music on the harp; for God is my Defense, his Stronghold and Fortress, and the God of my mercy, who furnished so many evidences of His gracious feeling toward David, many more than he deserved. David's praise is taken up by all believers, especially on account of their deliverance from the power of their great enemies, Satan, world, and flesh.
