Rabbi Ben Ezva
-----Written by Browning
Not on the vulgar mass
Called 'work',must sentence pass,
Things done,that took the eye and had the price;
O'er which ,from level stand,
The low world laid its hand,
Found straight way to its mind,could value in a trice:
But all,the world's coarse thumb
And finger failed to plumb,
So passed in making up the main account;
All instincts immature,
All purposes unsure,
That weighed not
