Jerusalem Gaude / Jerusalem Rejoice

Jerusalem gaude guadio magno,

Jerusalem rejoice, be glad and joyful,
for there shall come unto thee a Savior,  alleluia.

This Gregorian antiphon does not quote any scripture text directly. Instead it echos and rings with allusion to Zechariah 9:9, "Shout for joy, O Daughter of Jerusalem: behold your king will come to you..." and Isaiah 52:9 "Burst into songs of joy together, you ruins of Jerusalem, for the LORD has comforted his people, he has redeemed Jerusalem." and Zephaniah 3:14 "Sing, O Daughter of Zion; shout aloud, O Israel! Be glad and rejoice with all your heart, O Daughter of Jerusalem!"
