In this chapter the last of the four sets of seven covenant consequences outline in Leviticus 26 are poured out on the land. Its the seven bowls of wrath. And note... its on the 'land' they are poured out. But even more interesting is the explanation of 'Armageddon.... or more specifically Har Meggido - and how this symbol of a lying spirit which leads to destruction occurred twice previously in Israel/Judah and now occurs a third time to Jerusalem.
