John Gill Commentary Amos 1:14

"But I will kindle a fire in the wall of Rabbah, and it shall devour the palaces thereof, with shouting in the day of battle, with a tempest in the day of the whirlwind;" — Amos 1:14 (ASV)

But I will kindle a fire in the wall of Rabbah Which was the metropolis of the children of Ammon, and their royal city, (2 Samuel 12:26) . This is to be understood of an enemy that should destroy it, perhaps Nebuchadnezzar; or of war being kindled and raised in their country; this place being put for the whole; (See Gill on Jeremiah 49:2).

and it shall devour the palaces thereof ; the palaces of the king, and his nobles:

with shouting in the day of battle ; with the noise of soldiers when they make their onset, or have gained the victory; see (Jeremiah 49:2) ;

with a tempest in the day of the whirlwind ; denoting that this judgment should come suddenly, and at an unawares, with great force, irresistibly; and a tempest added to fire, if literally taken, must spread the desolation more abundantly, and make it more terrible.
