The acknowledgment of God, on the contrary, makes morality the very essence of the Divine nature, and the unchangeable rule for the life of man. CHAPTER IV _THE DECALOGUE--ITS FORM_ DEUT. v. 1-21. As the fourth chapter belongs to the speech which concludes the legislative portion of Deuteronomy both in contents and language (see Chapter XXIII.), we shall pass on now to the fifth chapter, which begins with a recital of the Decalogue. As has already been pointed out, the main trunk of the Book of Deuteronomy is a repetition and expansion of the Law of the Covenant contained in Exod. xx.-xxiii.[22] Now, both in Exodus and Deuteronomy, before the more general and detailed legislation, we have the Decalogue, or the Ten Words, as it is called, in substantially the same form; and the question immediately arises as to the age at which this beautifully systematised and organised code of fundamental laws came into existence. Whatever its origin, it is an exceedingly remarkable document. It touches the fundamental principles of religious and moral life with so sure a hand that at this hour, for even the most civilised nations, it sums up the moral code, and that so effectively that no change or extension of it has ever been proposed. That being its character, it becomes a question of exceeding interest to decide whether it can justly be referred to so early a time as the days of Moses. In both the passages where it occurs it is represented as having been given to the people at Horeb by Yahweh Himself, and it is made the earliest and most fundamental part of the covenant between Him and Israel. It would accordingly seem as if a claim were made for it as a specially early and specially sacred law. Now, much as critics have denied, there have been found very few who deny that in the main some such law as this must have been given to Israel in Moses' day. Even Kuenen admits as much as that in his _History of the Religion of Israel_. The only commandment of the ten he has difficulty in accepting is the second, which forbids the making of any graven image for worship. That, he thinks, cannot have been in the original Decalogue, not because of any peculiarity of language, or because of any incoherency in composition, but simply because he cannot believe that at that early day the religion of Yahweh could have been so spiritual as to demand the prohibition of images. But his reasons are extremely inadequate; more especially as he admits that the Ark was the Mosaic Sanctuary, and that in it there was no image, as there was none in the Temple at Jerusalem. That Yahweh was worshipped under the form of a calf at Horeb, and afterwards in Northern Israel at Bethel and elsewhere, proves nothing. A law does not forthwith extinguish that against which it is directed, for idolatry continued even after Deuteronomy was accepted as the law. Moreover, if, as Kuenen thinks, calf-worship had existed in Israel before Moses, it was not unnatural that it took centuries
