adder quotes

Theyare as venomous as the poison of a serpent: even like the deaf adder that stoppeth her ears; Which refuseth to hear the voice of the charmer: charm he never so wisely.

-Book of Common Prayer
Psalm 58:4^5.

It was not meant for human eyes, That combat on the shabby patch Of clods and trampled earth that lies Somewhere beneath the sodden skies For eye of toad or adder to catch.

- Edwin Muir
  The Labyrinth,'The Combat'.
