O Come, O Come Emmanuel

"O Come, O Come, Emmanuel" was originally used in the medieval church liturgy as a series of antiphons-short musical statements that were sung for the week of vesper services just before Christmas Eve. Each of these antiphons greets the anticipated Messiah with one of the titles ascribed Him throughout the Old Testament: Wisdom, Emmanuel, The Lord of Might, The Rod of Jesse, Dayspring, and The Key of David. from cbn.com

O come, O come, Emmanuel And ransom captive Israel
That mourns in lonely exile here Until the Son of God appear
Rejoice! Rejoice! Emmanuel Shall come to thee, O Israel.
O come, Thou Rod of Jesse, free Thine own from Satan's tyranny
From depths of Hell Thy people save
And give them victory o'er the grave
Rejoice! Rejoice! Emmanuel Shall come to thee, O Israel.
O come, Thou Day-Spring, come and cheer Our spirits by Thine advent here
Disperse the gloomy clouds of night And death's dark shadows put to flight.
Rejoice! Rejoice! Emmanuel Shall come to thee, O Israel.
O come, Thou Key of David, come, And open wide our heavenly home;
Make safe the way that leads on high, And close the path to misery.
Rejoice! Rejoice! Emmanuel Shall come to thee, O Israel.
O come, O come, Thou Lord of might, Who to Thy tribes, on Sinai's height,
In ancient times did'st give the Law, In cloud, and majesty and awe.
Rejoice! Rejoice! Emmanuel Shall come to thee, O Israel.
