Ellicott's 8 volume commentary on the entire Bible A Bible Commentary for English Readers is $35 in CP and has proven its worth to me by penetrating a morphological mystery in 2Chronicles 34.25. I don't own this work in hard copy, but the fact that this volume did what my ~15,000 book library and a frenetic online search could not has proven its value to me.
Let's get this work into production and any of you who are more familiar with this work if you can sing its praises I would much appreciate it. You can read about the mystery solved in this thread https://community.logos.com/forums/p/171712/992737.aspx#992737
