7 as a season of beauty upon the mountains, as the feet of one preaching glad tidings of peace, as one preaching good news: for I will publish thy salvation, saying, O Sion, thy God shall reign.
8 For the voice of them that guard thee is exalted, and with the voice together they shall rejoice: for eyes shall look to eyes, when the Lord shall have mercy upon Sion.
9 Let the waste places of Jerusalem break forth joy together, because the Lord has had mercy upon her, and has delivered Jerusalem.
10 And the Lord shall reveal his holy arm in the sight of all the nations; and all the ends of the earth shall see the salvation that from our God.
