My favorite Advent hymn. It dates back to at least the 12th century, though some say the 9th.

The Latin version is the one I learned as a child…at least the alto part. In Latin. But plainchant is better without harmony, especially for such an ancient hymn.

There are many versions of this on YouTube, lots of them with all the verses. This young man chose only a few but I settled on his rendition because of his unusual voice.

 

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 thee, O Israel.

Oh, come, Oh, come, Thou Rod of Jesse, free
Thine own from that Satan’s tyranny;
From depths of hell Thy people you will save
And give them victory o’er the grave.
Rejoice! Rejoice! Emmanuel
Shall come to thee, O Israel.
Shall come to thee, O Israel.

Oh, come, Oh, come, Thou King of David, come
And open wide your heavenly home:
Make safe the way that leads us on high
And close the path of misery, by and by.
Rejoice! Rejoice! Emmanuel
Shall come to thee, O Israel.

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