Exodus (Hebrew שמות shemòt, "names," from the incipit; Greek Έξοδος èxodos, "exit," Latin Exodus) is the second book of the Hebrew Torah and the Christian Bible.
It is written in Hebrew and, according to the hypothesis most shared by scholars, its final editing, by unknown authors, is placed in the VI-V century B.C. in Judea, on the basis of previous oral and written traditions (see Documentary Hypothesis), constituting the first nucleus around which the writing of the Bible would have been composed.
It is composed of 40 chapters. In the first 14 it describes the Jews' stay in Egypt, their enslavement and miraculous liberation through Moses, while in the remaining chapters it describes the Jews' stay in the Sinai desert. The period described is traditionally referred to 1250-1200 BC (then in the thirteenth century before Christ, and precisely at the time of Pharaoh Merneptah), while according to other scholars the Exodus of the Jews from Egypt would be referred to 1500 BC (under the pharaoh Amenophis II).
