Unwholesome weeds take root with precious flowers;
The adder hisses where the sweet birds sing;
What virtue breeds iniquity devours:
We have no good that we can say is ours
But ill-annexed Opportunity
Or kills his life or else his quality.
O Opportunity, thy guilt is great!
’Tis thou that executes! the traitor’s treason;
Thou set’st the wolf where he the lamb may get;
Whoever plots the sin, thou point’st the season;
