New Defender's Study Bible Notes
2:20 northern army. This striking prophecy had a precursive fulfillment in the overnight slaying of the Assyrian host that had laid siege to Jerusalem (Isaiah 37:36). Its ultimate fulfillment will apparently be in the almost equally sudden destruction of the vast armies of Gog and Magog by God (Ezekiel 38:21-22). In both cases, the army is a “northern army” and in both cases the great numbers of dead men will cause an “ill savour” (note Ezekiel 39:11). The “east sea” possibly means the Caspian Sea; the “utmost sea” is the Mediterranean.
