Matazoth---wafers of unleavened bread---To remind us of the fact that the Israelites did not have time to wait for yeast bread to rise to be ready to move when God said. (For the Christian this reminds us to live so that we are always "ready to go" When Jesus returns. Also yeast sometimes represented the evil in the world. God wants his people to be pure.)
Maror---bitter herbs, usually freshly grated horse-radish or other bitter herbs, pungent vegetable such as onion. These herbs are a reminder of the bitter suffering in Egyptian slavery. They are dipped in salt water to signify the tears of bitter suffering. (For the Christian, this reminds us that many have suffered that we may know the joy of the good news of Jesus. So in our Celebration, we remember the great cost.)
Haroseth---A mixture of chopped apples, nuts, cinnamon, and wine. This represents the mortar with which the Israelites were force to make bricks to build Pharaoh's great cities. ( See Exodus 2:11-14 and 5:4-23)
The shank of bone of a lamb---This is the symbol of the lamb that was sacrificed for sins ( For the Christian, this represents Jesus, God's own gift of a perfect Lamb for the sins of all.
There are still the elements of the roasted egg, parsley or watercress, wine or grape juice and Elijah's cup. Then of course, the empty tomb. For me I learned that so often I look only the cross. I feel sad, but really I should focus on that empty tomb and see it not as a tragedy but a triumph.
