But even on this view it would follow that from the time of Josiah, when Deuteronomy was accepted as the completest expression of the will of God, the doctrine that ritual and sacrifice as well as penitence were essential things in true religion was known, and not only known but accepted as the orthodox opinion. Putting aside, then, the question whether sacrifice was acknowledged by the prophets before this or not, they must have accepted it from this point onward, unless they denied to Deuteronomy the authority which it claimed and which the nation conceded to it. Jeremiah clearly must have assented to it, for his style and his thought have been so closely moulded on this book that some have thought he may have been its author. In any case he did not repudiate its authority; and all the prophets who followed him must have known of this view, and also that it had been sanctioned by that book which was made the first Jewish Bible. We have here, at all events, the keynote of the supremacy of moral duty over Divine commands concerning ritual which distinguishes the prophetic teaching in Micah and elsewhere, joined with the enforcement of ritual observances. But there are few purely prophetic passages which raise the higher demand so high as it is raised here. To love and fear God are anew declared to be man's supreme duties, and the author presses these home by arguments of various kinds. Again he returns to the election of Israel by Yahweh, without merit of theirs; and to bring home to them how much this means, the Deuteronomist exhibits the greatness of their God, His might, His justice, and His mercy, which, great as it is to His chosen people, is not confined to them, but extends to the stranger also. This most gracious One they are to serve by deeds, to Him they are to cleave, and they are to swear by Him only, that is, they are solemnly to acknowledge Him to be their God in return for His undeserved favour. For their very existence as a nation is a wonder of His power, since they were only a handful when they went down to Egypt, and now were "as the stars of heaven for multitude." Then once more, in chapter xi., he repeats his one haunting thought that love is to be the source of all worthy fulfilment of the law; and he endeavours to shed abroad this love to God in their hearts by reminding them once more of all the marvels of their deliverance from Egypt, and of their wilderness journey. Their God had delivered them first, then chastised them for their sins, and had trained them for the new life that awaited them in the land promised to their fathers.
