The divine impressions and influences he was under, to prepare him for those heavy tidings (v. 22): The hand of the Lord was upon me before he came, and had opened my mouth to speak to the house of Israel what we had in the former part of this chapter. And now he was no more dumb; he prophesied now with more freedom and boldness, being by the event proved a true prophet, to the confusion of those that contradicted him. All the prophecies from ch. xxiv. to this chapter have relation purely to the nations about, it is probable that the prophet, when he received them from the Lord, did not deliver them by word of mouth, but in writing; for he could not Say to the Ammonites, Say unto Tyrus, Say unto Pharaoh, &c., so and so, but by letters directed to the persons concerned, as Zacharias, when he could not speak, wrote; and herein he was as truly executing his prophetic office as ever. Note, Even silenced ministers may be doing a great deal of good by writing letters and making visits. But now the prophet's mouth is opened, that he may speak to the children of his people. It is probable that he had, during these three years, been continually speaking to them as a friend, putting them in mind of what he had formerly delivered to them, but that he never spoke to them as a prophet, by inspiration, till now, when the hand of the Lord came upon him, renewed his commission, gave him fresh instructions, and opened his mouth, furnished him with power to speak to the people as he ought to speak.
