History of Israel
Davis was also a student of the creationist theologian John C. Whitcomb. He and Whitcomb were friends and colleagues at Grace Theological Seminary; they co-authored the 1980 work "A History of Israel: From Conquest to Exile". GTS removed Whitcomb from his teaching position in 1990; Davis, then president of the seminary, said that Whitcomb had been a "source of division" at GTS, while Whitcomb attributed the falling out to doctrinal differences.
