Exodus 12:17-25 New International Version (NIV)
17 “Celebrate the Festival of Unleavened Bread, because it was on this very day that I brought your divisions out of Egypt. Celebrate this day as a lasting ordinance for the generations to come. 18 In the first month you are to eat bread made without yeast, from the evening of the fourteenth day until the evening of the twenty-first day. 19 For seven days no yeast is to be found in your houses. And anyone, whether foreigner or native-born, who eats anything with yeast in it must be cut off from the community of Israel. 20 Eat nothing made with yeast. Wherever you live, you must eat unleavened bread.”
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. 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. None of you shall go out of the door of your house until morning. 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.
24 “Obey these instructions as a lasting ordinance for you and your descendants.25 When you enter the land that the Lord will give you as he promised, observe this ceremony.
Passover and the Festival of Unleavened Bread became an annual remembrance of how God delivered the Hebrews from Egypt. Each year the Hebrews would pause and remember the day when the angel of death passed over their homes. This was a time to give thanks to God for saving them from death. It was also a time to be thankful for bringing them out of slavery. Have you experienced deliverance? The day you were delivered from spiritual death and slavery to sin, you saved. The Lord’s Supper is our remembrance of new life and freedom. The next time struggles and bad times come your way, pause to remember how God has delivered you in the past. Focus on God’s promises of your new life with him.
