Who wrote the book?
As with Genesis, early Jewish traditions name Moses as the most likely and best qualified person to have authored Exodus. This theory is
supported by a number of factors. Moses’s unique education in the
royal courts of Egypt certainly provided him the opportunity and ability to pen these works (Acts 7:22). Internal evidence (material found within the text of Exodus itself ) adds support for Moses’s authorship. Many conversations, events, and geographical details could be known only by an eyewitness or participant. For example, the text reads: “Moses then wrote down everything the Lord had said,” (Exodus 24:4 NIV).
Additionally, other biblical books refer to “the law of Moses” ( Joshua 1:7; 1 Kings 2:3), indicating that Exodus, which includes rules and
regulations, was written by Moses. Jesus Himself introduced a quote from Exodus 20:12 and 21:17 with the words, “For Moses said” (Mark 7:10), confirming His own understanding of the book’s author.
The title “Exodus” comes from the Septuagint, which derived it from the primary event found in the book, the deliverance from slavery and “exodus” or departure of the Israelite nation out of Egypt by the hand of Yahweh, the God of their forefathers.

Where are we?
Exodus begins in the Egyptian region called Goshen. The people then traveled out of Egypt and, it is traditionally believed, moved toward the southern end of the Sinai Peninsula. They camped at Mount Sinai, where Moses received God’s commandments.
The book covers a period of approximately eighty years, from shortly before Moses’s birth (c. 1526 BC) to the events that occurred at Mount Sinai in 1446 BC.
Why is Exodus so important?
In Exodus we witness God beginning to fulfill His promises to
Abraham, Isaac, and Jacob. Though the children of Israel were
enslaved in a foreign land, God miraculously and dramatically
delivered them to freedom. He then established Israel as a
theocratic nation under His covenant with Moses on Mount Sinai. The ten plagues, the Passover, the parting of the Red Sea, the fearsome
majesty of God’s presence at Mount Sinai, the giving of the Ten
Commandments, the building of the tabernacle . . . these events from Exodus are foundational to the Jewish faith. And they provide
crucial background context to help future readers of Scripture
understand the entire Bible’s message of redemption. The frequency of references to Exodus by various biblical writers, and even Jesus’s own words, testify to its importance.

What's the big idea?
The overall theme of Exodus is redemption—how God
delivered the Israelites and made them His special
people. After He rescued them from slavery, God
provided the Law, which gave instructions on how the people could be consecrated or made holy. He
established a system of sacrifice, which guided them in appropriate worship behavior. Just as significantly, God provided detailed directions on the building of His
tabernacle, or tent. He intended to live among the
Israelites and manifest His shekinah glory (Exodus 40:34–35)—another proof that they were indeed His people.
The Mosaic Covenant, unveiled initially through the Decalogue (Ten Commandments), provides the
foundation for the beliefs and practices of Judaism, from common eating practices to complex worship
regulations. Through the Law, God says that all of life relates to God. Nothing is outside His jurisdiction.
