The springtime festivals of Passover and the Feast of Unleavened Bread memorialize the redemption and exodus of the children of Israel from Egyptian slavery. God commands in Exodus 13:3, 8-9 to keep the Feast of Unleavened Bread as a memorial of what He did in delivering them from the Egyptians. The story of their deliverance from Egypt associates unleavened bread with God's act of rescue. In Exodus 12:3, 6, God instructs them to take a lamb from the flock on the tenth day, and on the fourteenth day to kill it at twilight. They are to take some of the blood and put it on the two doorposts and on the lintel of the houses where they eat it, as explained in Exodus 12:7. God declares in Exodus 12:13 that the blood shall be a sign, and when He sees the blood, He will pass over them, ensuring the plague does not destroy them when He strikes the land of Egypt. Additionally, in Exodus 12:17-18, God commands the observance of the Feast of Unleavened Bread, for on that day He brought their armies out of Egypt, instructing them to eat unleavened bread from the fourteenth to the twenty-first day of the first month, with no leavening found in their houses for seven days. Finally, Exodus 12:50-51 recounts that the children of Israel did as the Lord commanded Moses and Aaron, and on that very day, the Lord brought them out of the land of Egypt according to their armies.

The Feast of Unleavened Bread stands as a solemn memorial of God's mighty deliverance of His people from Egypt, a place known as the house of bondage. As recorded in Exodus 13:3, Moses instructed the people to remember the day they were brought out of Egypt by the strength of the LORD's hand, emphasizing that no leavened bread shall be eaten. Further, in Exodus 13:7-9, the command is clear: unleavened bread must be consumed for seven days, with no leaven to be seen among them, as a sign and memorial of what the LORD did in bringing them out of Egypt with a strong hand. This deliverance from Egypt, referenced repeatedly as the house of bondage, underscores the primary reason for the feast. The phrase, used thirteen times in Scripture, carries a weighty reminder of the slavery from which God freed His people, subtly warning against rebellion that could lead back to such bondage. In Exodus 20:1-6, God introduces His commandments by declaring His authority as the One who brought Israel out of the land of Egypt, out of the house of bondage, linking His deliverance directly to the obligation to obey His laws to remain free. Similarly, in Deuteronomy 5:6 and 5:15, God reiterates this preamble before the commandments, reminding His people of their past slavery in Egypt and connecting their deliverance by His mighty hand to the specific command to keep the Sabbath day. This connection highlights that adherence to His instructions, including Sabbath observance, is foundational to avoiding re-enslavement. In Deuteronomy 8:11-14, God warns against forgetting Him after prosperity, lest they forget the LORD who brought them out of Egypt, from the house of bondage. This caution extends to Deuteronomy 13:1-5, where God emphasizes the danger of false prophets enticing His people away from the way He commanded, reminding them of their redemption from the house of bondage as a call to remain faithful to His path. These passages collectively affirm that God's deliverance from Egypt is not merely a historical event but a continual call to live according to His instructions, ensuring that the freedom He granted does not become vain through a return to spiritual slavery.
