Israel is Reclaimed and Reunited

11:10 At that time a root from Jesse will stand like a signal flag for the nations. Nations will look to him for guidance, and his residence will be majestic.

Isaiah 18:3

18:3 All you who live in the world,

who reside on the earth,

you will see a signal flag raised on the mountains;

you will hear a trumpet being blown.
