Good name in man and woman

Iago
Good name in man and woman, dear my lord,
Is the immediate jewel of their souls.
Who steals my purse steals trash. ‘Tis something, nothing;
‘Twas mine, 'tis his, and has been slave to thousands.
But he that filches from me my good name
Robs me of that which not enriches him
And makes me poor indeed.
Othello
By heaven,  I'll know thy thoughts.
Iago
You cannot, if my heart were in your hand,
Nor shall not, whilst 'tis in my custody.
Othello
Ha?
Iago
O, beware, my lord, of jealousy!
It is the green-eyed monster which doth mock
The meat it feeds on. That cuckold lives in bliss
Who, certain of his fate, loves not his wronger;
But O, what damnèd minutes tells he o'er
Who dotes, yet doubts; suspects, yet strongly loves!
Othello
O misery!
Iago
Poor and content is rich, and rich enough;
But riches fineless is as poor as winter
To him that ever fears he shall be poor.
Good God,  the souls of all my tribe defend
From jealousy!
Othello
Why, why is this?
Think'st thou I'd make a life of jealousy,
To follow still the changes of the moon
With fresh suspicions? No. To be once in doubt
Is once to be resolved. Exchange me for a goat
When I shall turn the business of my soul
To such exsufflicate and blown surmises,
Matching thy inference. ‘Tis not to make me jealous
To say my wife is fair, feeds well, loves company,
Is free of speech, sings, plays, and dances well.
Where virtue is, these are more virtuous.
Nor from mine own weak merits will I draw
The smallest fear or doubt of her revolt,
For she had eyes, and chose me. No, Iago,
I'll see before I doubt; when I doubt, prove;
And on the proof, there is no more but this:
Away at once with love or jealousy.
Iago
I am glad of this, for now I shall have reason
To show the love and duty that I bear you
With franker spirit. Therefore, as I am bound,
Receive it from me. I speak not yet of proof.
Look to your wife; observe her well with Cassio;
Wear your eyes thus, not jealous nor secure.
I would not have your free and noble nature,
Out of self-bounty, be abused. Look to ‘t.
I know our country disposition well.
In Venice they do let God see the pranks
They dare not show their husbands. Their best conscience
Is not to leave ‘t undone, but keep ‘t unknown.
Othello
Dost thou say so?
Iago
She did deceive her father, marrying you,
And when she seemed to shake and fear your looks,
She loved them most.
Othello
And so she did.
Iago
Why, go to, then!
She that, so young, could give out such a seeming,
To seel her father's eyes up close as oak,
He thought 'twas witchcraft! But I am much to blame.
I humbly do beseech you of your pardon
For too much loving you.
Othello
I am bound to thee forever.
