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).

And thy speech shall be low out of the dust "And from out of the dust thou shalt utter a feeble speech" - That the souls of the dead uttered a feeble stridulous sound, very different from the natural human voice, was a popular notion among the heathens as well as among the Jews. This appears from several passages of their poets; Homer, Virgil, Horace. The pretenders to the art of necromancy, who were chiefly women, had an art of speaking with a feigned voice, so as to deceive those who applied to them, by making them believe that it was the voice of the ghost. They had a way of uttering sounds, as if they were formed, not by the organs of speech, but deep in the chest, or in the belly; and were thence called εγγαστριμυθοι, ventriloqui: they could make the voice seem to come from beneath the ground, from a distant part, in another direction, and not from themselves; the better to impose upon those who consulted them. Εξεπιτηδες το γενος τουτο τον αμυδρον ηχον επιτηδευονται, ἱνα δια την ασαφειαν της φωνης τον του ψευδους αποδιδρασκωσιν ελεγχον. Psellus De Daemonibus, apud Bochart, 1 p. "These people studiously acquire, and affect on purpose, this sort of obscure sound; that by the uncertainty of the voice they may the better escape being detected in the cheat. "From these arts of the necromancers the popular notion seems to have arisen, that the ghost's voice was a weak, stridulous, almost inarticulate sort of sound, very different from the speech of the living.

And thou shalt be brought down,.... To the ground, and laid level with it, even the city of Jerusalem, as it was by the Romans; and as it was predicted by Christ it would, Luke 19:44 though some understand this of the humbling of the inhabitants of it, by the appearance of Sennacherib's army before it, and of which they interpret the following clauses:

and shalt speak out of the ground, and thy speech shall be low out of the dust; which some explain of the submissive language of Hezekiah to Sennacherib, and of his messengers to Rabshakeh, 2 Kings 18:14 as Aben Ezra and Kimchi; but it is expressive of the great famine in Jerusalem, at the time of its siege by the Romans, when the inhabitants were so reduced by it, as that they were scarce able to speak as to be heard, and could not stand upon their legs, but fell to the ground, and lay in the dust, uttering from thence their speech, with a faint and feeble voice:

and thy voice shall be as one that hath a familiar spirit, out of the ground, and thy speech shall whisper out of the dust: or peep and chirp, as little birds, as Jarchi and Kimchi, as those did that had familiar spirits; and as the Heathen oracles were delivered, as if they came out of the bellies of those that spoke, or out of caves and hollow places in the earth; and this was in just retaliation to these people, who imitated such practices, and made use of such spirits; see Isaiah 8:19.

And thou shalt be brought down, and shalt speak out of the {d} ground, and thy speech shall be low out of the dust, and thy voice shall be, like a medium, out of the ground, and thy speech shall whisper out of the dust.

(d) Your speech will be no longer be so lofty but abased and low as the very charmers who are in low places and whisper, so that their voice can scarcely by heard.

29:4 And thou - Thou who now speakest so loftily, shall be humbled, and with a low voice, beg the favour of thine enemies. As one - Who, that they might possess the people with a kind of reverence and horror, used to deliver their answers with a low voice, from some cave under the ground.

whisper: Heb. peep, or, chirp

4. Jerusalem shall be as a captive, humbled to the dust. Her voice shall come from the earth as that of the spirit-charmers or necromancers (Isa 8:19), faint and shrill, as the voice of the dead was supposed to be. Ventriloquism was doubtless the trick caused to make the voice appear to come from the earth (Isa 19:3). An appropriate retribution that Jerusalem, which consulted necromancers, should be made like them!

29:1-8 Ariel may signify the altar of burnt-offerings. Let Jerusalem know that outward religious services will not make men free from judgements. Hypocrites never can please God, nor make their peace with him. God had often and long, by a host of angels, encamped round about Jerusalem for protection and deliverance; but now he fought against it. Proud looks and proud language shall be brought down by humbling providences. The destruction of Jerusalem's enemies is foretold. The army of Sennacherib went as a dream; and thus the multitudes, that through successive ages fight against God's altar and worship, shall fall. Speedily will sinners awake from their soothing dreams in the pains of hell.
