Spurgeon · Verse 10
Faith leads on to strong desire for the realization of the promise, and hence the practical question, Who will bring me into the strong city? who will lead me into Edom? The difficulty is plainly perceived. Petra is strong and hard to enter: the Psalmist warrior knows that he cannot enter the city by his own power, and he therefore asks who is to help him. He asks of the right person, even of his Lord, who has all men at his beck, and can say to this man, "show my servant the road", and he will show it, or to this band, "cut your way into the rock city", and they will assuredly do it. Of Edom it is written by Obadiah", The pride of thine heart hath deceived thee, thou that dwellest in the clefts of the rock, whose habitation is high; that saith in his heart, who shall bring me down to the ground? Though thou exalt thyself as the eagle, and though thou set thy nest among the stars, thence will I bring thee down, saith the Lord." David looked for his conquest to Jehovah's infinite power and he looked not in vain.
