During Passover, bread and four cups of wine are an important part of the meal.
The dinner begins with a first cup of wine when two prayers of blessing to God are offered - one for the feast, and one for the cup of wine.
Unleavened bread is eaten, dipped by hand into a dish of sauce.
The first part of the Hallel (taken from Psalm 112-113) is sung, and the second cup if wine is drunk as a memorial to the Exodus.
The lamb is eaten along with the herbs and unleavened bread, and the third cup of wine is drunk with thanksgiving to God for the meal and hope for the future.
The rite ends with a fourth cup of wine (hope for the Messiah) and the singing of the rest of the Hallel.
Scripture scholars often pose the question: Which of the four cups did Jesus raise and say "This is my blood" during the Passover meal with the apostles?
