Isaiah 29:4

And shalt speak out of the ground - (see the note at Isaiah 8:19). The sense here is, that Jerusalem, that had been accustomed to pride itself on its strength I would be greatly humbled and subdued. Its loud and lofty tone would be changed. It would use the suppressed language of fear and alarm as if it spoke from the dust, or in a shrill small voice, like the pretended conversers with the dead.

And thy speech shall whisper out of the dust - Margin, ‘Peep,’ or ‘Chirp,’ (see the note at Isaiah 8:19).
