27 In that day your mouth will be opened to him who has escaped, and you shall speak, and be no more mute: so you will be a sign to them; and they shall know that I am Yahweh.

Ezekiel had been employed four years in foretelling the calamities about to come to pass. He had been utterly disregarded by the inhabitants of Jerusalem, and received with apparent respect but with real incredulity by those in exile. Now until the city had been actually taken, the voice of prophecy should cease, so far as God's people were concerned. Hence the intervening series of predictions relating to neighboring and foreign nations Ezek. 25-32. After which the prophet's voice was again heard addressing his countrymen in their exile. This accounts for the apparently parenthetical character of the next eight chapters.
In that day shall thy mouth be opened - What is, When some one who shall have escaped from Jerusalem, having arrived among the captives, shall inform them of the destruction of the city, the temple, the royal family, and the people at large; till then he might suppress his tears and lamentations. And we find from Ezekiel 33:21, that one did actually escape from the city, and informed the prophet and his brethren in captivity that the city was smitten.
Thus he was not only a prophet to foretell such things, but he was also a sign or portent, shadowing them out by circumstances in his own person and family; and thus the prediction, agreeing so perfectly with the event, proved that the previous information was from the Lord.
In that day shall thy mouth be opened to him which is escaped,.... And shall freely converse with him about the several facts and circumstances of taking and burning the city and temple, and of the usage of the inhabitants:
and thou shalt speak, and be no more dumb; for from this time to the taking of Jerusalem, which was about eighteen months, the prophet had nothing to say to the people of the Jews, and so was dumb with respect to them; but was employed in prophesying against other nations, as the following chapters show, unto chapter thirty three, in which we have an account of the messenger that escaped to him; but after that his mouth was opened, and he prophesied to them again:
and thou shalt be a sign unto them; as they will then own and acknowledge:
and they shall own that I am the Lord; who have foretold these things, and accomplished them.
No more dumb - From this prophecy for eighteen months during the siege, he does not prophesy of Israel, but of other nations. Thou shalt be a sign - Until the event shall convince the Jews, thou shalt by sign, signify to them, what is coming.
