He who the sword of heaven will bearMetonymy
Should be as holy as severe,
Pattern in himself to know,
Grace to stand, and virtue go;
More nor less to others paying
Than by self-offenses weighing.
Shame to him whose cruel striking
Kills for faults of his own liking.

O, what may man within him hide,
Though angel on the outward side!

Twice treble shame on Angelo,
To weed my vice, and let his grow.Metaphor
O, what may man within him hide,
Though angel on the outward side!Metaphor
How may likeness made in crimes,
Making practice on the times,
To draw with idle spiders’ strings
Most ponderous and substantial things.Metaphor
Craft against vice I must apply.
With Angelo tonight shall lie
His old betrothèd but despisèd.
So disguise shall, by th’ disguisèd,Antanaclasis
Pay with falsehood false exactingAntanaclasis
And perform an old contracting.
