In that day will I cause the horn of the house of Israel to bud forth,.... Not at the time of Egypt's destruction, unless it can be thought that this refers to the advancement of Daniel in the court of Babylon; or to the taking of Jehoiachin out of prison, and setting his throne above the rest of the kings; which events came to pass a little after this: but rather this respects the time of Egypt's restoration forty years after, when Cyrus came to the throne, and proclaimed liberty to the Jews to return to their own land, and build their city and temple, under the government of Zerubbabel their prince: besides, it may not be limited to either of these times, but may regard the famous day, when the kingdom of Israel, in a spiritual sense, should flourish under the Messiah, the Horn of salvation, and Branch of David, often promised to bud forth, and was fulfilled in Jesus, Ps 132:17.
The Targum is,"in that day will I bring redemption to the house of Israel.''And I will give thee the opening of the mouth in the midst of them; in prophecy among them, as the Targum; who after this, might deliver other prophecies, though we have no account of them; or he should have boldness and courage when he and they should see his prophecies fulfilled, by which it would appear that he was a true prophet of the Lord:and they shall know that I am the Lord; who sent the prophet, and from whom he had these prophecies, and by whom they were fulfilled.
