Thus for themselves and us good speed imploring,
Those spirits went beneath a weight like that
We           feel in dreams, all, sore beset,
But with unequal anguish, wearied all,
Round the first circuit, purging as they go,
The world's gross darkness off: In our behalf
If there vows still be offer'd, what can here
For them be vow'd and done by such, whose wills
Have root of goodness in them?
