In exchange for God's miracle work, the Jewish people are instructed to follow a rigorous, strident set of laws. These laws were delivered by God to Moses, who transmits them to the laypeople. The covenant between God and the Jews demands obedience to these scriptural laws. The detailed description of the construction of the tabernacle offered in Exodus illustrates the extent of the spiritual code that binds the "chosen people" with their Almighty.
The central theological theme of the Biblical book of Exodus is that God and humanity enter into a sacred contract. To break the contract means breaking a promise to God, a horrible offense punishable by the wrathful Creator. Ascription to the covenant will mean that God will continue to watch over the Jewish people and ensure their heritage in the Promised Land.
