O come, O come, Emmanuel,
And ransom captive Israel,
That mourns in lonely exile here
Until the Son of God appear

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.

O come, Thou Rod of Jesse,
Free Thine own from Satan’s tyranny;
From depths of hell Thy people save,
And give them vict’ry o’er the grave

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

O come, Thou Key of David, come,
And open wide our heav’nly home;
Make safe the way that leads on high,
And close the path to misery.

CHORUS
Rejoice! Rejoice! Emmanuel
Shall come to thee, O Israel.
