Rejoice! Not tedious seventies' soft-porn, but the mighty frowning litso of the God of the Hebrews.

Rejoice! rejoice, Emmanuel
Shall come to thee oh Israel

Oh come, oh come Emmanuel
Redeem thy captive Israel
That into exile drear has gone
Far from the face of God's dear son

Oh come, oh come thou David's key
The royal door swings wide and free
Safe-guard for us the Heavenward road
And bar the way to death's black abode

Come, oh come thou dayspring bright
Pour on our souls thy healing light
Dispel the long night's lingering gloom
And pierce the shadows of the tomb

Oh come, oh come Adonai
Who in thy glorious majesty
From that high mountain clothed with awe
Gavest thy folk the elder law

Translated by John Mason Neale, from Psalteriolum Cantionum Catholicarum
