Zephaniah 3:6 “I have cut off nations, their fortresses are devastated; I have made their streets desolate, with none passing by, their cities are destroyed; there is no one, no inhabitant. [7] I said, ‘Surely you will fear Me, you will receive instruction’–so that her dwelling would not be cut off, despite everything for which I punished her. But they rose early and corrupted all their deeds.
God reminds Israel of the former nations (including Samaria) that had fallen in times past. Even Israel’s introduction as an established nation began with the displacement of seven kingdoms that comprised Canaan after they were led out of Egypt.
