The Book of Exodus is the second book of the Bible. It is a narrative of the Exodus, the origin myth of the Israelites leaving slavery in Biblical Egypt through the strength of their deity named Yahweh, who according to the story chose them as his people. The Israelites then journey with the legendary prophet Moses to Mount Sinai, where Yahweh gives the 10 commandments and they enter into a covenant with Yahweh, who promises to make them a "holy nation, and a kingdom of priests" on condition of their faithfulness. He 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 conquer Canaan, which has earlier, according to the myth of Genesis, been promised to the "seed" of Abraham, the legendary patriarch of the Israelites.

Abrahamic religions believe in the Mosaic covenant, also known as the Sinaitic covenant, which refers to a covenant between the Israelite tribes and their God, including their proselytes, not limited to the ten commandments, nor the event when they were given, but including the entirety of laws that their patriarch Moses delivered from God in the five books of Torah.
