The first half of Exodus is a narrative account of the Israelites' escape from Egyptian bondage and their journey to Mount Sinai. This deliverance account includes the story of Moses, Yahweh's chosen leader. Moses mediated a series of disasters that culminated in the Israelites' release. Overcoming all obstacles, including a great expanse of sea, the Israelites made their way through the wilderness until they came to the mountain of God, where the terms of the covenant were revealed to them through Moses.
