If you are interested to study the Old Testament in more depth and you are not sure what Old Testament Survey to look at, you may want to take a look at the following book (Encountering the Old Testament: A Christian Survey ) by Arnold and Beyer.
This book usually costs about $50.00 and is now on sale at CBD for only $14.99 (see the link above).
The survey is clearly written with an evangelical perspective and has many great pictures, charts and insights. It is fairly easy to read and understand.
See a few reviews of the book here.
P.S. It seems that the low price is due to the fact that a new edition has been issued. Of course – that is more expensive.
