How pleasant are the footsteps of the herald upon the mountains announcing peace, heralding good tidings... The voice of your lookouts, they raise their voice, they sing glad song in unison; with their own eyes they will see that Hashem returns to Zion: Burst out, sing glad song in unison, O ruins of Jerusalem, for Hashem will have comforted His people; He will have redeemed Jerusalem: Isaiah 52:7-9
