In an effort to better understand the cultural and linguistic background of the authors of the Old Testament (and the Book of Mormon for that matter) lately, I have also been looking for good books. Based on recommendations from Ben Spackman I have been reading
I also recently purchased the NRSV cultural background Study Bible. I highly recommend the two books above since they provide excellent background and context in general before starting the Old Testament and then a Study Bible to use along with the Come, Follow Me studies.
I also use Biblehub.com quite a lot.
