O thou enemy, destructions are come to a perpetual end. It is better to translate, with the Revised Version, The enemy are come to an end; they are desolate for ever—a continuance of the hyperbole already noticed in the preceding verse.
And thou hast destroyed cities; their memorial is perished with them; rather, and as for the cities thou hast destroyed, their very memory has perished. This could only be an anticipation. It was fulfilled in the complete disappearance from history of the names of Zoba, Beth-rehob, and Tob, after the victory described in 2 Samuel 10:13, 2 Samuel 10:14.
