What is the book in the Old Testament that is all names?
There isn't a book in the Old Testament (or the New Testament)
that is all names. However, there are places in the Old Testament
that has a lot of names listed in them. Numbers has a lot of names
in it because it has a record of the census taken of the children
of Israel while they were in the desert. But that only accounts for
a couple of chapters, not the entire book which has 36 chapters.
Joshua also has a lot of names in it because it's telling who gets
what in the promised land. I Chronicles has more names than any
other book in the Old Testament because it is a historical record
of people from Adam to Abraham. The 1st 9 chapters are all names in
a book with a total of 29 chapters. Ezra also has a long list of
names in chapters 2, 8 and 10. Nehemiah has a list in chapters 7,
10 and 12.
