“Although a doctor of divinity, Luther relied for several years almost exclusively on the Latin version of the Scriptures. Very few professors knew Greek, and still less, Hebrew.
Luther had acquired a superficial idea of Hebrew at Erfurt from Reuchlin’s Rudimenta Hebraica. The Greek he learned at Wittenberg, we do not know exactly when, mostly from books and from his colleagues, Johann Lange and Melanchthon.
As late as Feb. 18th, 1518, he asked Lange, “the Greek,” a question about the difference between ἀνάθημα and ἀνάθεμα, and confessed that he could not draw the Greek letters”. – Schaff, History of the Christian Church, Vol. 7, Sec. 27.
Don’t be like Luther.
