The book of Exodus friend.
The book tells how the Isrealites leave slavery in Egypt through the strength of Yahweh, the god who has chosen Israel as his people. Led by their prophet Moses they journey through the wilderness to Mount Sinai, where Yahweh promises them the land of Canaan (the "Promised Land") in return for their faithfulness. Israel enters into a covenant with Yahweh who gives them their laws and instructions to build the Tabernackle, the means by which he will come here from heaven and dwell with them and lead them in a holy war to possess the land, and then give them peace.
Traditionally ascribed to Moses himself, modern scholarship sees the book as initially a product of the Babylonians exile (6th century BCE), based on earlier written and oral traditions, with final revisions in the Persian post xcilic period (5th century BCE). Carol Myers in her commentary on Exodus suggests that it is arguably the most important book in the Bible, as it presents the defining features of Israel's identity: memories of a past marked by hardship and escape, a binding covenant with God, who chooses Israel, and the establishment of the life of the community and the guidelines for sustaining it.[
