Analysis of At Liberty I Sit and See

At liberty I sit and see
      Them, that have erst laugh'd me to scorn,
    Whipp'd with the whip that scourged me:
      And now they ban that they were born.

I see them sit full soberly
      And think their earnest looks to hide;
    Now, in themselves, they cannot spy
      That they or this in me have spied.

I see them sitting all alone,
    Marking the steps, each word and look;
  And now they tread where I have gone,
    The painful path that I forsook.

Now I see well I saw no whit
    When they saw well, that now are blind;
  But happy hap hath made me quit,
    And just judgement hath them assign'd.

I see them wander all alone,
    And tread full fast, in dreadful doubt,
  The self-same path that I have gone:
    Blessed be hap that brought me out!

At liberty all this I see,
    And say no word but erst among,
  Smiling at them that laugh'd at me:
    Lo, such is hap! Mark well my song!
