O thou enemy, destructions are come to a perpetual end: and thou hast destroyed cities; their memorial is perished with them. Destructions are come to a perpetual end - Rather, "The enemy is desolated for ever; for thou hast destroyed their cities, and their memory is perished with them." Multitudes of the cities of the Canaanites have perished so utterly that neither name nor vestige remains of them.
