'O Opportunity, thy guilt is great! (877)
'Tis thou that executest the traitor's treason: (878)
Thou set'st the wolf where he the lamb may get; (879)
Whoever plots the sin, thou 'point'st the season; (880)
'Tis thou that spurn'st at right, at law, at reason;
And in thy shady cell, where none may spy him, (882)
Sits Sin, to seize the souls that wander by him.
