“Yahweh will go out and fight against those nations.” Yahweh will fight through the work of His Messiah, Jesus Christ, just as he heals through Jesus Christ (cp. Isa. 63:1-6). Yahweh’s battle will be the Battle of Armageddon, when the enemy nations will gather on earth to fight with the Lord Jesus and his armies as they come from heaven (Rev. 19:11-21).
