The book of Exodus is also divided between the Yahwist and P, and the usual understanding is that the Priestly writer(s) were adding to an already-existing Yahwist narrative. Chapters 1–24 (from bondage in Egypt to God's appearances at Sinai) and chapters 32–34 (the golden calf incident) are from the Yahwist and P's additions are relatively minor, noting Israel's obedience to the command to be fruitful and the orderly nature of Israel even in Egypt. P was responsible for chapters 25–31 and 35–40, the instructions for making the Tabernacle and the story of its fabrication.
