“This sacrifice in essence of two things
Consisteth; one is that, whereof ’t is made,
The covenant the other.  For the last,
It ne’er is cancell’d if not kept:  and hence
I spake erewhile so strictly of its force. 
For this it was enjoin’d the Israelites,
Though leave were giv’n them, as thou know’st, to change
The offering, still to offer.  Th’ other part,
The matter and the substance of the vow,
May well be such, to that without offence
It may for other substance be exchang’d. 
But at his own discretion none may shift
The burden on his shoulders, unreleas’d
By either key, the yellow and the white. 
Nor deem of any change, as less than vain,
If the last bond be not within the new
Included, as the quatre in the six. 
No satisfaction therefore can be paid
For what so precious in the balance weighs,
That all in counterpoise must kick the beam. 
Take then no vow at random:  ta’en, with faith
Preserve it; yet not bent, as Jephthah once,
Blindly to execute a rash resolve,
Whom better it had suited to exclaim,
‘1 have done ill,’ than to redeem his pledge
By doing worse or, not unlike to him
In folly, that great leader of the Greeks: 
Whence, on the alter, Iphigenia mourn’d
Her virgin beauty, and hath since made mourn
Both wise and simple, even all, who hear
Of so fell sacrifice.  Be ye more staid,
O Christians, not, like feather, by each wind
Removable:  nor think to cleanse ourselves
In every water.  Either testament,
The old and new, is yours:  and for your guide
The shepherd of the church let this suffice
To save you.  When by evil lust entic’d,
Remember ye be men, not senseless beasts;
Nor let the Jew, who dwelleth in your streets,
Hold you in mock’ry.  Be not, as the lamb,
That, fickle wanton, leaves its mother’s milk,
To dally with itself in idle play.” 
     Such were the words that Beatrice spake: 
These ended, to that region, where the world
Is liveliest, full of fond desire she turn’d. 
     Though mainly prompt new question to propose,
Her silence and chang’d look did keep me dumb. 
And as the arrow, ere the cord is still,
Leapeth unto its mark; so on we sped
Into the second realm.  There I beheld
The dame, so joyous enter, that the orb
Grew brighter at her smiles; and, if the star
Were mov’d to gladness, what then was my cheer,
Whom nature hath made apt for every change! 
     As in a quiet and clear lake the fish,
If aught approach them from without, do draw
Towards it, deeming it their food; so drew
Full more than thousand splendours towards us,
And in each one was heard:  “Lo! one arriv’d
To multiply our loves!” and as each came
The shadow, streaming forth effulgence new,
Witness’d augmented joy.  Here, reader! think,
If thou didst miss the sequel of my tale,
To know the rest how sorely thou wouldst crave;
