Ezekiel 39:5-6

Gog would fall in the open fields because the Lord had decreed His judgment. Yahweh would also destroy Gog’s homeland, Magog, and the remote homelands of his allies (the coastlands, cf. Ezekiel 26:15; Ezekiel 26:18; Ezekiel 27:3; Ezekiel 27:6-7; Ezekiel 27:15; Ezekiel 27:35), and those who safely inhabited these regions. This would teach them that He is God.
