The Origination of Passover
Moses had been instructed to lead God's people out of Egypt and save them from the evil and ungodly Pharaoh. Because of Pharaoh's disbelief in the power of the One True God, Yahweh sent a series of ten plagues upon the Egyptians: the Nile turned to blood and at various times the land was filled with frogs, gnats, flies, hail, locusts, and darkness. In one awesome act of God's ultimate authority, He sent one final devastating plague: every firstborn of every household would be annihilated.
In His mercy towards His people, God would shield the Israelites from such unmerciful judgement if they would follow the instructions He gave to Moses and Aaron. The specific instructions are outlined in Exodus 12:1-11. In sum, each family was to take a lamb and all households were to slaughter their lambs at the same time at twilight after a certain number of days. Then they were commanded to paint the sides and top of their doorways with some of this blood. Once this was done and all the meat of the lamb was eaten in accordance with God's instructions, God would spare the Israelites from death. This is what the Lord said:
"On that same night I will pass through Egypt and strike down every firstborn -- both men and animals -- and I will bring judgement on all the gods of Egypt. I am the Lord. The blood will be a sign for you on the houses where you are; and when I see the blood, I will pass over you. No destructive plague will touch you when I strike Egypt. This is a day you are to commemorate; for the generations to come you shall celebrate it as a festival to the Lord -- a lasting ordinance" (Exodus 12:12-14).
Accounts of what happened can be found in all four gospels -- Matthew 26:17-27:10; Mark 14:12-72; Luke 22:1-65; John 13:1-18:27.
Sedar
The Seder meal consists of six highly symbolic elements: matzah, a roasted shank bone, parsley or green herbs, the top of a horseradish, charoset, and an egg. On each plate are three piece of matzah. Two of these pieces represent the traditional loaves used in the ancient Temple during festivals and the third piece symbolizes Passover. The roasted lamb bone connotes the sacrificial Passover lamb. Herbs symbolize springtime growth. The horseradish represents the bitter years of slavery in Egypt; charoset, a mixture of fruit and ground nuts soaked in wine, represents the mortar used in Egypt; and the egg represents the chagigah.
