23:2 Book of the Covenant. Scholars debate the precise contents of this book or scroll. Although Ex. 20–23 is called the “Book of the Covenant” (Ex. 24:7), it is unlikely that only these chapters in Exodus are meant. Judging from the kinds of reform Josiah pursues in vv. 4–24, the book was a version of Deuteronomy (22:8 note) or a larger group of laws including Deuteronomy.
