Isaiah 27:12-13

12At that time, the Lord will shake the tree! He will do that to his people everywhere from the River Euphrates to the Stream of Egypt. Then he will bring together all of you, one by one, you Israelite people.

13At that time, they will hear the sound of a loud trumpet. Then people who were dying in exile in Assyria will come. People who went away into Egypt will also come. They will worship the Lord on his holy hill in Jerusalem.
