Certain Uncertainty
The essay explores the deep connection between the primordial Serpent (Nachash) and Haman, noting that both were punshished after a span of seventy verses. It argues that their power lies in exploiting moments of 'safek' (doubt) and uncertainty, such as Chava's slight hesitation or Bnei Yisrael's questioning of Hashem's presence; the antidote to this 'Amalekite' energy is the fierce certainty and emunah demonstrated by the children Mordechai encountered.
