Isaiah 30:30-31

30, 31. Isaiah 30:27-28; Isaiah 30:27-28, depict the approach of the great judge; here the description of the judgment begins.

Voice… heard God’s “voice” is “heard,” also, as the delivered ones shout their song, and the action of his arm is seen image of corporal chastisement.

Indignation… anger Manifested as fury, under figure of an animal snorting, with flames bursting from its nostrils, leaving behind a scattering, the work of a tempest, and stones of hail. Here, again, our prophet overrides modern rhetorical refinement, and mixes fire and hail together. The Assyrian can stand no such a rush of destructive forces.

Which smote with a rod That is, the hitherto persecuting Assyrian. The smiter is now himself smitten with a vengeance.
