The Final Gathering of the Remnant

Isaiah 27:12-13

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.
