The book of Exodus describes the Israelites' journey from slavery in Egypt to freedom. It begins with the Israelites enslaved in Egypt and ends with them receiving the Law from God at Mount Sinai and constructing the Tabernacle as a place of worship. Key events include Moses leading the Israelites out of Egypt after ten plagues, the first Passover, crossing the Red Sea, receiving manna and water from God in the wilderness, and being given the Ten Commandments at Sinai. The central theme is God redeeming his people from bondage and establishing them as His chosen nation with Himself as their God.
