Isaiah 27:12-13

12And it shall come to pass in that day, that Jehovah shall beat out from the flood of the river unto the torrent of Egypt, and ye shall be gathered one by one, [ye] children of Israel. 13And it shall come to pass in that day, [that] the great trumpet shall be blown; and they shall come that were perishing in the land of Assyria, and the outcasts in the land of Egypt, and they shall worship Jehovah in the holy mountain at Jerusalem.
