Exodus 12:18 "On that evening, you shall eat unleavened bread"

On the fifteenth night of the month of Nisan, the holiday of Pesach begins.

We commemorate the story of Pesach by eating the very same type of unleavened bread our ancestors ate as they made their exodus from Egypt.

We are obligated to eat the Matzot on the first night of Pesach.

On the other days of Pesach, we continue to eat Matzah because we may not eat any Chametz.
