So covenantal history moves forward. The people murmur against God and break the covenant, yet God gives them manna from heaven, water from the rock, a pillar of fire to lead them, a symbol of his presence in the tabernacle, and healing by the brazen serpent. Israel crosses the Jordan and enters the promised land. The Exodus event dominates the skyline of Old Testament history. It towers over the consciousness of Israel for all time to come.
All future history is understood in the light of that event.
This deliverance becomes the pattern for all future deliverances. The Old Testament presents a recurring pattern of captivity and restoration. This is a witness to the infidelity of man and to the faithfulness of God. His undeserving people have sold themselves into captivity. But God delivers them because He is the covenant-keeping God.
