For when saw he that well-nigh everything
Which needs of man most urgently require
Was ready to hand for mortals, and that life,
As far as might be, was established safe,
That men were lords in riches, honour, praise,
And eminent in goodly fame of sons,
And that they yet, O yet, within the home,
Still had the anxious heart which vexed life
          with torments of the mind,
And raved perforce with angry plaints, then he,
Then he, the master, did perceive that 'twas
The vessel itself which worked the bane, and all,
However wholesome, which from here or there
Was gathered into it, was by that bane
Spoilt from within,--in part, because he saw
The vessel so cracked and leaky that nowise
'T could ever be filled to brim; in part because
He marked how it polluted with foul taste
Whate'er it got within itself.
