BASSANIO.
Why dost thou whet thy knife so earnestly?

SHYLOCK.
To cut the forfeiture from that bankrupt there.

GRATIANO.
Not on thy sole, but on thy soul, harsh Jew,
Thou mak'st thy knife keen; but no metal can,
No, not the hangman's axe, bear half the keenness
Of thy sharp envy. Can no prayers pierce thee?

SHYLOCK.
No, none that thou hast wit enough to make.

GRATIANO.
O, be thou damn'd, inexecrable dog!
And for thy life let justice be accus'd.
Thou almost mak'st me waver in my faith,
To hold opinion with Pythagoras
That souls of animals infuse themselves
Into the trunks of men. Thy currish spirit
Govern'd a wolf who, hang'd for human slaughter,
Even from the gallows did his fell soul fleet,
And, whilst thou lay'st in thy unhallow'd dam,
Infus'd itself in thee; for thy desires
Are wolfish, bloody, starv'd and ravenous.
