Oh Come, Oh Come, Enmanuel
Oh come, oh come, Emmanuel
And ransom captive Israel
That mourns in lonely exile here
Until the Son of God Appear
Rejoice! Rejoice! Emmanuel
Shall come to you, O Israel!
Oh come, O Root of Jesse, free
Your own from Satan's tyranny
From depths of hell your people save
And bring them vict'ry o'er the grave
Oh come, O Dayspring from on high,
And cheer us by your drawing nigh;
Disperse the gloomy clouds of night
And death's dark shadows put to flight
Oh come, O Key of David, come
And open wide our heavenly home.
Make safe the way that leads on high
And close the path to misery.
