What Does Deuteronomy 17:18 Mean?

(18) **He shall write him a copy of this law.**—This phrase is the source of the Greek title of the book, *Deuteronomion, *or in English, Deuteronomy. The word appears also in Joshua 8:32. The English conveys the right sense of the word, which primarily denotes repetition. In Hebrew it is *Mishneh, *the name afterwards given to the “text” of the Talmud, of which the idea is to repeat the law; though it is a somewhat peculiar repetition, in which *minutiœ *are chiefly dealt with, and weightier matters left out. There are traces of this direction (1) in the coronation of Joash (2Chronicles 23:11, “they gave him the testimony;” (2) in the reign of Jehoshaphat, who had the Book of the Law taught to his people (2Chronicles 17:9); and (3) in the delivery of the book when discovered in the Temple to Josiah (2Chronicles 34:18), and in the effect of the perusal of it upon that king. But it is singular that we do not hear of the Book of the Law in connection with David and Solomon. Possibly, as David was a prophet himself, and not only a king, it may be thought unnecessary to make special mention of his study of the law. In many things he acted upon the direct commands of God to himself or to his seers. We must not forget that the true king of Israel is He whose special mission it was “to fulfil the law and the prophets.” “Lo, I come, *in the volume of the book it is written of *me, I delight to do thy will, O my God: *yea, thy law is within my heart.”*
