Exodus 13:3
This is the first mention of eating unleavened bread in context with the events of the day. It is not the first time that unleavened bread is mentioned in terms of the Feast of Unleavened Bread, as that appears in Exodus 12. Here, Moses is inspired to write down that we are to eat unleavened bread because of what the Lord did.

Moses, inspired, commands eating unleavened bread because of what the Lord did—His deliverance from Egypt. The prohibition on leavened bread ties directly to this deliverance so people understand why they observe it. Though Unleavened Bread is commonly held to be about putting sin out, God overwhelmingly emphasizes His deliverance, not human effort. Eating unleavened bread solidifies the memory of what is being observed. This feast is a memorial, causing God's people to remember God's merciful deliverance from slavery, which undergirds everything else. Without the correct focus, feasts lose their God-given power, becoming mere good times with a religious gloss, as happened in Israel and Judah. The unleavened bread is a sign to the Israelites for what God has done.
