Translation:
1. O come, O 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.
2. O come, Thou Wisdom from on high,
And order all things, far and nigh;
To us the path of knowledge show,
And teach us in her ways to go.
Rejoice! Rejoice! Emmanuel
Shall come to thee, O Israel.
3. O come, Adonai, Lord of might,
Who to Thy tribes, on Sinai’s height,
In ancient times didst give the law
In cloud and majesty and awe.
Rejoice! Rejoice! Emmanuel
Shall come to thee, O Israel.
4. O come, Desire of nations, bind
All peoples in one heart and mind;
Bid envy, strife and quarrels cease;
Fill the whole world with heaven’s peace
Rejoice! Rejoice! Emmanuel
Shall come to thee, O Israel.
