Exodus 12:11 "This is how you are to eat it: with your cloak tucked into your belt, (Not only was the Passover meal to be prepared in haste, but their eating of it should also reflect the same hurried rush because their departure from Egyptian bondage would be immediate. Their garments should be belted at their waists the way the people wore them when they were at work and needed to move about with purpose and intent. God's people were about to embark on another kind of work, the work of the Lord's rescue and escape and freedom as they departed the place of their enslavement.) your sandals on your feet and your staff in your hand. Eat it in haste; it is the Lord's Passover." (Though slaves didn't wear shoes, and certainly didn't wear shoes inside their homes, they needed to put on shoes to be ready for their imminent journey and to represent their being slaves no longer. The meal of the roasted lamb, the bitter greens, and bread without yeast, all to fuel them for their journey, as well as to reflect the haste in its preparation and their departure, would be a reminder that this deliverance was the miraculous work of the Lord. It is His deliverance. It is His Passover. He alone had provided the means for attaining this remarkable freedom, It was not the result of their efforts, only His, still another reminder for us of the later full and complete release from sin that He has provided for us through the work of Jesus Christ Himself alone. As we belt up our garments to be ready for the new work at hand that requires our intentional departure from the life of oppression we have endured, as we step into the shoes of freed people ready for the journey into freedom in Christ, the Lord has declared today that He has redeemed us with the Blood of the Lamb, and we still experience today the passing over, the Passover, of the judgment of the Lord and the immediate entry into new life in Him.)
