The celebration of Passover and the Festival of Unleavened Bread is meant to launch the new year for God’s people. It is a feast given to commemorate a deliverance that is about to take place, but has not yet been fulfilled. As the people keep vigil for the dawn of their deliverance, God gives them something to feast on that makes them strong for the journey so that, when their time to depart comes, they walk out filled, fueled, and ready to arise.
