The two great classics in this field:

John D. Davis.  A dictionary of the Bible

Still as relevant as ever.

David Noel Freedman, Allen C. Myers, Astrid B. Beck. Eerdmans Dictionary of the Bible

which has recently been updated.  (Note: Some pages are missing from this file.)

Cruden's Concordance is a related reference work.  (Again, some pages are missing from this file.)
