Isaiah 7:14; Isaiah 8:8

14 "Therefore the Lord Himself will give you a sign: Behold, a virgin will be with child and bear a son, and she will call His name Immanuel.
8 "Then it will sweep on into Judah, it will overflow and pass through, It will reach even to the neck; And the spread of its wings will fill the breadth of your land, O Immanuel.
