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:
But I will kindle a fire in the wall of Rabbah - the capital of Ammon: meaning 'the Great.' Distinct from Rabbah of Moab. Called Philadelphia, afterward, from Ptolemy Philadelphus.
With a tempest - i:e., with an onset swift, sudden, and resistless as a hurricane.
In the day of the whirlwind - parallel to the 'day of battle;' therefore meaning 'the day of the foe's tumultuous assault.'
