Fourth Sunday of Advent

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

O come, Thou Wisdom from on high,
Who orderest all things mightily;
To us the path of knowledge show,
And teach us in her ways to go.

O come, Thou Rod of Jesse, free
Thine own from Satan’s tyranny;
From depths of hell Thy people save,
And give them victory over 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 heavenly home;
Make safe the way that leads on high,
And close the path to misery.

O come, O come, great Lord of might,
Who to Thy tribes on Sinai’s height
In ancient times once gave the law
In cloud and majesty and awe.

O come, Thou Root of Jesse’s tree,
An ensign of Thy people be;
Before Thee rulers silent fall;
All peoples on Thy mercy call.

O come, Desire of nations, bind
In one the hearts of all mankind;
Bid Thou our sad divisions cease,
And be Thyself our King of Peace.

I've said some things about why I like this hymn here.
