How beautiful upon the mountains are the feet of him that bringeth good tidings, that publisheth peace; that bringeth good tidings of good, that publisheth salvation; that saith unto Zion, Thy God reigneth! 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. Break forth into joy, sing together, ye waste places of Jerusalem: for the LORD hath comforted his people, he hath redeemed Jerusalem. The LORD hath made bare his holy arm in the eyes of all the nations; and all the ends of the earth shall see the salvation of our God.
These verses picture the return of the Jews from their worldwide dispersion. As the exiles travel over the mountains to Zion, they are preceded by heralds who proclaim the good news of the Messiah’s reign. The watchmen on the walls of Jerusalem sing with joy as they see the Lord returning at the head of the multitude. Jerusalem itself is summoned to celebrate the Lord’s mighty deliverance.
