Kadesh (Sanctification) and Urchatz (Hand Washing)

The Seder begins with the recitation of the kiddush over wine (the first of four glasses throughout the ceremony). The kiddush proclaims the holiness of the holiday. Then everyone at the table takes a drink from their cup.

Next, water is poured over the hands to symbolize ritual purification. Traditionally a pitcher is used to pour water over the right hand followed by the left, and a blessing is usually said, but not at this point of the Seder.
