The Dake Bible was first published in 1961 and is the result of the work of a man named Finnis Jennings Dake (1902-1987), a Pentecostal minister. As a result of a criminal conviction, his ordination as a pastor with the Assemblies of God was revoked. The charges were eventually dismissed. He later joined the Church of God but in later years became independent of any denomination.
The Dake Bible itself is an extensive work, with some 35,000 commentary notes and over 50,000 cross references, using the King James Version as its basic text. Most Bible scholars consider Dake’s notes to be the personal viewpoints of Finnis Jennings Dake rather than objective or strictly based on the Bible. Dake wrote from a Charismatic viewpoint, so the Dake Bible definitely is of that persuasion.
There are many study Bibles to choose from, and some are better than others. Many people like to use several different study Bibles when they do an in-depth study, because each set of notes carries with it the personality of the person(s) who helped edit it.
The bottom line is that, like any study Bible, the Dake Bible has its good points and its bad points. Due to its strong Pentecostal/Charismatic emphasis, there are far better study Bibles available than the Dake Bible. The Dake Bible can be useful as part of an overall study, but due to its strong Charismatic emphasis, it should not be used as a primary study tool.
