Hi Dominique,
The short answer is yes. The book of Exdus relates entirely to the Exodus of Israel from Egypt and the establishment of Israel as God’s people. This was such a significant event in the history of Israel and ultimately in God plans of redemption that it warrants its own book.
I assume from your question that you may not have read it? If that is so then let me encourage you to do so. It is a significant event for Christians to understand for almost everything that Jesus did, he did as a fulfilment of ideas in Exodus.
cheers
David
