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 didst give the law,
In cloud, and majesty, and awe.
Rejoice! Rejoice! Emmanuel
Shall come to thee, O Israel.
