A Great Trumpet — Isaiah 27:10–13

For the fortified city is solitary, a habitation deserted and forsaken, like the wilderness: there shall the calf feed, and there shall he lie down, and consume the branches thereof. When the boughs thereof are withered, they shall be broken off; the women shall come, and set them on fire; for it is a people of no understanding: therefore he that made them will not have compassion upon them, and he that formed them will show them no favor.

And it shall come to pass in that day, that Jehovah will beat off his fruit from the flood of the River unto the brook of Egypt; and ye shall be gathered one by one, O ye children of Israel. And it shall come to pass in that day, that a great trumpet shall be blown; and they shall come that were ready to perish in the land of Assyria, and they that were outcasts in the land of Egypt; and they shall worship Jehovah in the holy mountain at Jerusalem.
