Lucas 24:44

In the law of Moses, and in the prophets, &c.— The Old Testament was in those days divided into three parts; first, the law, which contained the five books of Moses; secondly, the hagiographa, which contained divine hymns and moral instructions, and went under the general title of the Psalms, because they were esteemed the most eminent, and were placed at the head of those writings; and thirdly, the prophets, which contained not only the books merely prophetical, but those likewise which were historical, written by prophetic men.
