The book of exodus (from ancient greek: ἔξοδος, romanized: éxodos; hebrew: שְׁמוֹת šəmōṯ, "names") is the second book of the bible. it narrates the story of the exodus, in which the israelites leave slavery in biblical egypt through the strength of yahweh, the god who has chosen them as his people. the israelites then journey with the prophet moses to mount sinai, where yahweh promises them the land of canaan (the "promised land") in return for their faithfulness. there, they enter into a covenant with yahweh, who gives them their laws and instructions to build the tabernacle, the means by which he will come from heaven and dwell with them and lead them in a holy war to possess the land, and then give them peace.
