The Exodus is the central event of the Old Testament. Its themes of liberation, wilderness, Passover, covenant, and God's dwelling are central for the whole Bible. It tells the story of God calling Moses to be the prophet through whom God will lead the people to freedom from slavery in Egypt and their struggles to learn faithfulness in the wilderness where God makes covenant with them. The 10 commandments form the ethical core of this covenant, while the instructions for building a tent of worship accentuate God's intention to dwell in the midst of the people.
