I. The Passover
Now let’s look at the background of the Lord’s Supper. It was the night to celebrate the Passover. Remember what significance blood had with this festival. Exodus 12 says,
12:21  Then Moses summoned all the elders of Israel and said to them, “Go at once and select the animals for your families and slaughter the Passover lamb.
12:22  Take a bunch of hyssop, dip it into the blood in the basin and put some of the blood on the top and on both sides of the doorframe. Not one of you shall go out the door of his house until morning.
12:23  When the LORD goes through the land to strike down the Egyptians, he will see the blood on the top and sides of the doorframe and will pass over that doorway, and he will not permit the destroyer to enter your houses and strike you down.

What was put on the door post?

II. The Bread
In Exodus 13:6-10, God gives meaning to the unleavened bread, He said, “13:6  For seven days eat bread made without yeast and on the seventh day hold a festival to the LORD.
13:7  Eat unleavened bread during those seven days; nothing with yeast in it is to be seen among you, nor shall any yeast be seen anywhere within your borders.
13:8  On that day tell your son, ‘I do this because of what the LORD did for me when I came out of Egypt.’
13:9  This observance will be for you like a sign on your hand and a reminder on your forehead that the law of the LORD is to be on your lips. For the LORD brought you out of Egypt with his mighty hand.
13:10  You must keep this ordinance at the appointed time year after year.
Eating unleavened bread became a reminder of the time when God delivered the children of Israel out of bondage.

Coming out of egypt was a reminder of being set free from

III. Communion
1 Peter 1:18  For you know that it was not with perishable things such as silver or gold that you were redeemed from the empty way of life handed down to you from your forefathers,
1:19  but with the precious blood of Christ, a lamb without blemish or defect.
