A.T. Robertson, the towering genius of Greek grammar, calls wisdom “the practical use of knowledge.” F.J.A. Hort, in his painstaking commentary, terms it “that endowment of heart and mind which is needed for right conduct in life.” J.H. Ropes describes it as “the supreme and divine quality of the soul which man knows and practical righteousness.” And Ralph Martin in his recent study states. “For the Jewish mind wisdom meant practical righteousness in everyday living.”
