These chapters describe an attack of Gentile countries against "Israel." Some have concluded that this attack will occur PRIOR to the return of Jesus Christ. Others believe that it is the same attack which is described in the 20th chapter of the book of Revelation; that is, at the END of the Millennium or about 1,000 years AFTER Christ's return.
"You are the light of the world. A city that is set on a hill cannot be hidden."
-Matthew 5:14
