Isaiah 52: 8-9,
8 Thy watchmen shall lift up the voice; with the voice together shall they sing: for they shall see eye to eye, when the Lord shall bring again Zion.
9 Break forth into joy, sing together, ye waste places of Jerusalem: for the Lord hath comforted His people, He hath redeemed Jerusalem.
What a time of joy and celebration when the watchers–those who stand on the walls looking for Him–will shout together as they all clearly see Messiah coming. The phrase eye to eye did not mean then what it means to us today. Rather, it indicates they will all see the same thing, and there will be no doubt or debate about what is happening. Everyone’s eyes will see Messiah.
Even the waste places, the places that have been utterly ruined, will join in the song of rejoicing when Jesus comes to comfort His people, and to redeem Jerusalem from it’s long history of sorrow.
Again, this passage has a two-fold application. It can address God’s redemption of Israel from Babylon, certainly. But the context of this whole chapter is the Second Advent, with great emphasis on the final victory Messiah will have over all the enemies of Jerusalem forever. The time of weeping is over. The time of rejoicing has come to stay.
