Lo, How a Rose E'er Blooming

This German folk carol is believed to be from the fifteenth or early sixteenth century. There are many versions of the lyrics, some have up to twenty three verses. When it's sung in English, these lyrics are most often used:
Lo, how a Rose e’er blooming
From tender stem hath sprung!
Of Jesse’s lineage coming,
As men of old have sung.
It came, a flow’ret bright,
Amid the cold of winter,
When half spent was the night.
Isaiah ’twas foretold it,
The Rose I have in mind;
With Mary we behold it,
The virgin mother kind.
To show God’s love aright,
She bore to men a Savior,
When half spent was the night.
This Flow’r, whose fragrance tender
With sweetness fills the air,
Dispels with glorious splendor
The darkness everywhere.
True man, yet very God,
From sin and death He saves us,
And lightens every load.
