The symbolic meaning of pouring poison somebodys’
ear, reminds a lot of people of the symbolic meaning of the snake in The Garden
of Eden. The snake, or the devil, talked to Eve about The Tree of the Knowledge
of Good and Evil. This is an example of the snake giving false words into Eve’s
ears, to misleading her into doing wrong, misleading Adam too. They both had
poisoned words into their ears, like those in “Hamlet”.
