29. The Lord's people will sing as they do when they celebrate a religious festival at night. The Lord is Israel's mighty rock, and his people will be as happy as they are when they follow the sound of flutes to the mountain where he is worshipped.
30. The Lord will get furious. His fearsome voice will be heard, his arm will be seen ready to strike, and his anger will be like a destructive fire, followed by thunderstorms and hailstones.
31. When the Assyrians hear the Lord's voice and see him striking with his iron rod, they will be terrified.
