The biblical Book of Exodus contains 40 chapters.
Exodus is the second book of the Hebrew Bible and the Christian Old Testament. Its 40 chapters tell the story of the Israelites’ oppression in Egypt, Moses’s calling, the plagues, the departure from Egypt, the journey through the wilderness, the covenant at Sinai, and the construction of the Tabernacle.
The chapter divisions are editorial organizing tools rather than part of the original ancient composition. Medieval Jewish scribes and Christian scholars helped establish the systems of chapter and verse numbering used in modern printed Bibles. As a result, chapter numbers do not necessarily mark changes in the underlying narrative or literary structure.
Exodus is traditionally associated with Moses, although modern biblical scholarship commonly studies it as a text formed from several traditions and stages of composition. Its 40-chapter structure is consistent across standard English Bible editions, though verse numbering and translation wording can vary slightly.
