'So then he hath it when he cannot use it,
And leaves it to be master'd by his young;
Who in their pride do presently abuse it:
Their father was too weak, and they too strong,
To hold their cursed-blessed fortune long.
The sweets we wish for turn to loathed sours
Even in the moment that we call them ours.

'Unruly blasts wait on the tender spring;
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 executest the traitor's treason:
Thou set'st the wolf where he the lamb may get;
Whoever plots the sin, thou point'st the season;
'Tis thou that spurn'st at right, at law, at reason;
And in thy shady cell, where none may spy him,
Sits Sin, to seize the souls that wander by him.

'Thou makest the vestal violate her oath;
Thou blow'st the fire when temperance is thaw'd;
Thou smother'st honesty, thou murder'st troth;
Thou foul abettor! thou notorious bawd!
Thou plantest scandal and displacest laud:
Thou ravisher, thou traitor, thou false thief,
