Although the mitzvah of destroying Amalek cannot be fulfilled today
because we do not know who the descendants of Amalek are, we still have a
mitzvah to remember and develop the desire to eradicate evil. Then when
Eliyahu the Prophet will reveal who the descendants of Amalek are, we will
destroy them. May Hashem help us merit his arrival with Mashiach
speedily, in our days.
