Stay thy rash hand! ere to that hour
From which no Traveller can return.
All stain'd with sin, unfit to die,
Unsummon'd you presume to fly!—
The tube is rais'd, the die is cast—
Another moment is the last.
But, ere the awful scene is clos'd,
A guardian hand hath interpos'd;
And in this time of utmost need,
See Mentor rush to stay the deed,
