In this episode, we learn positive mitzvah #22, which is to remove chametz from your possession on the 14th day of Nissan.

• Chametz is when one of the five grains (wheat, barley, oat, spelt, rye) are mixed with water and left to rise for at least 18 minutes.
• One can remove chametz by eating, destroying it, throwing it out, or declaring it as ownerless.
• The deadline for this mitzva is the 14th day on the month of Nissan at midday.
  • The Sages made the deadline one hour earlier, so that people don't leave it for the last minute
• The Sages instituted that the night before this deadline, people should search their homes to find all their chametz ("Bedikat Chametz").
