We must of force dispense with this decree

King
We must of force dispense with this decree.
She must lie here on mere necessity.
Berowne
Necessity will make us all forsworn
Three thousand times within this three years' space;
For every man with his affects is born,
Not by might mastered, but by special grace.
If I break faith, this word shall speak for me:
I am forsworn on mere necessity.
So to the laws at large I write my name,
And he that breaks them in the least degree
Stands in attainder of eternal shame.
Suggestions are to other as to me,
But I believe, although I seem so loath,
I am the last that will last keep his oath.
