Barnes' Notes
Who will bring me into the strong city? - The strong city - the fenced, the fortified city - referred to here is doubtless the capital of Idumea. This was the celebrated city Petra, situated in the rocks, and so difficult to be taken by an enemy. For a description of it, see the notes at Isaiah 16:1. It was this city, as the capital of the land of Edom, which David was now so anxious to secure; and he asks, therefore, with interest, who among his captains, his mighty men, would undertake the task of conducting his armies there.
Who will lead me into Edom? - Into the capital, and thence into the whole land to subdue it. This was done under the combined command of Joab and Abishai his brother. See the notes at the title to the psalm.
