I will in Cassio’s lodging lose this napkin

I will in Cassio's lodging lose this napkin
And let him find it. Trifles light as air
Are to the jealous confirmations strong
As proofs of holy writ.

Trifles light as air
Are to the jealous confirmations strong
As proofs of holy writ

This may do something.
The Moor already changes with my poison;
Dangerous conceits are in their natures poisons,
Which at the first are scarce found to distaste,
But with a little act upon the blood
Burn like the mines of sulfur.

I did say so.
Look where he comes. Not poppy nor mandragora
Nor all the drowsy syrups of the world
Shall ever medicine thee to that sweet sleep
Which thou owedst yesterday.
