Veni, O Jesse virgula,
Ex hostis tuos ungula,
De specu tuos tartari
Educ et antro barathri.
Draw nigh, O Jesse’s Rod, draw nigh,
To free us from the enemy;
From Hell’s infernal pit to save,
And give us victory o’er the grave.
O come, thou Rod of Jesse’s stem
From every foe deliver them
That trust thy mighty power to save,
And give them victory o’er the grave.
O come, thou Branch of Jesse! draw
The quarry from the lion's claw;
From the dread caverns of the grave,
From nether hell, thy people save.
O come, Thou Rod of Jesse, free
Thine own from Satan's tyranny;
From depths of hell Thy people save,
And give them victory o'er the grave.
O come, Thou Root of Jesse's tree,
An ensign of Thy people be;
Before Thee rulers silent fall;
All peoples on Thy mercy call.
O come, thou Branch of Jesse’s Tree
Free them from Satan’s tyranny
That trust thy mighty power to save,
And give them Victory o’er the grave.
If translating literally, I'd very roughly translate the verse as : "Come, O branch of Jesse, / your own from the talon of foe, / your own from the caves of hell / and from the caverns of the abyss draw forth."
