We have come to a very important division in the book of Exodus, Roughly divided, chapters 1-18 deal with the exodus itself, from which the book gets its name; and then the second half, chapters 19-40, deals with the giving of the law. We think of Moses as the great emancipator, but he was also the lawgiver by the grace of God. And this matter of giving the law was very necessary if the Jewish people were to be formed into a true nation. Deliverance from slavery is one thing, but freedom without law leads to license—and license is only another form of slavery. So, what we find in the second half of the book is the work of God through Moses in providing the people with the law code.
