[8] Davis taught at Grace Theological Seminary from 1963 to 2003,[5] offering courses in Old Testament, Hebrew and Archaeology.
Davis published his account of visiting with Freeman and his congregation as a four-part series in the Warsaw Times-Union.
[6][7] He told the Associated Press that, in his view, Freeman was a "good theologian" who knew the Bible well, but his uncompromising stance on faith healing and the seclusion of his congregation had "resulted in personal tragedy for several people".
He and Whitcomb were friends and colleagues at Grace Theological Seminary;[13] they co-authored the 1980 work A History of Israel: From Conquest to Exile.
Interpreting the Psalms for Teaching and Preaching included contributions from Walter Kaiser and Eugene Merrill.
[2][5] Biblical Numerology received positive reviews from Raymond F. Surburg in The Springfielder and Charles Lee Feinberg in the Journal of the Evangelical Theological Society.
[16][17] Surburg wrote that the book was a "scholarly study" in an area (biblical numerology) that had suffered from a lack of mainstream attention, perhaps due to its association with "cranks and crackpots".
[16] Feinberg wrote that Davis was a "careful and sane scholar" and his book was a valuable contribution to the field.
[25][26] He wrote a weekly column called "Outdoor Scene" for the Warsaw, Indiana Times Union newspaper for 31 years, and has written several humour books about fishing.
[5][25] Hellen Ochs in The Republic recommended Real Fishermen Never Lie as "perfect for winter reading".
[28] Davis worked with the radio sportscaster Bob Chase as a colour commentator for Fort Wayne Komets hockey game broadcasts on WOWO (AM).
