I Know a Rose Tree

I know a Rose tree springing
Forth from an ancient root
As men of old we singing
From Jesse came the shoot
That bore a blossom bright
A-mid the cold of winter
When half spent was the night

O Flow'r, whose fragrance tender
With sweetness fills the air
Dispel in glorious splendor
The darkness ev'rywhere
True man, yet very God
From sin and death now save us
And share our ev'ry load
