And the LORD shall cause his glorious voice to be heard, and shall shew the lighting down of his arm, with the indignation of his anger, and with the flame of a devouring fire, with scattering, and tempest, and hailstones.
The Lord shall cause his glorious voice to be heard. Yahweh's "glorious voice," raised against the enemy (Isaiah 30:27), is again mentioned here, in contrast to the music (Isaiah 30:29) with which His people shall come to worship Him.
And shall show the lighting down of his arm (Isaiah 30:32; Psalms 38:2) - the descent of His arm in striking.
With scattering - with a blast that scatters; or an inundation ( nepets (H5311): from the Arabic sense) (Maurer). But the English version is more usual in Hebrew.
