The dictionary displayed on eInspiration.org is based on the Easton's Bible Dictionary.

Easton's Bible Dictionary generally refers to the Illustrated Bible Dictionary, Third Edition, by Matthew George Easton, M.A., D.D. (1823-1894), published in 1897 (three years after Easton's death) by Thomas Nelson. Because of its age, it is now a public domain resource. It contains nearly 4,000 entries relating to the Bible, from a 19th century Christian viewpoint. Despite its name, many of the entries in Easton's are encyclopedic in nature, though there are also short, dictionary-like entries. -Wikipedia
