John Calvin Commentary Psalms 60:9

"Who will bring me into the strong city? Who hath led me unto Edom?" — Psalms 60:9 (ASV)

Who will bring me into the fortified city? Anticipating an objection that might be raised, he then states that he looked to God to accomplish what remained to be done in capturing the fortified places of his enemies and consolidating his victories.

It might be said that, since a considerable number continued to resist his claims, the confident terms he had used were premature. God, however, had pledged His word that every nation that opposed him would be brought under his power, and in the face of remaining difficulties and dangers, he advances with the certainty of success.

By the fortified city, some understand Rabbah, the capital of the Moabites. Others, more probably, consider that the singular is used for the plural and that David alludes generally to the different cities under whose protection his enemies were determined to hold out. He declares that the same God who had crowned his arms with victory in the open field would lead him to besiege these cities.

To prove his legitimate call to govern, he again emphasizes the marks of divine favor his call had received by contrasting it with what preceded. “The God,” he says, “who had formerly rejected us and abandoned us to unsuccessful warfare, will now open before me the gates of hostile cities and enable me to break through all their fortifications.”
