"He that might the vantage best have took"

Alas alas!
Why, all the souls that were were forfeit once,
And He that might the vantage best have took
Found out the remedy.  How would you be
If He which is the top of judgement should
But judge you as you are?  O, think on that,
And mercy then will breathe within your lips
Like man new made.

     Isabella to Angelo, at Measure for measure II.2, ll. 96-103.
