(105) As, then, in Deuteronomy, we find not only the book of the law of Moses, or the greater part of it, but also many things inserted for its better explanation, I conjecture that this Deuteronomy is the book of the law of God, written, set forth, and explained by Ezra, which is referred to in the text above quoted. (106) Two examples of the way matters were inserted parenthetically in the text of Deuteronomy, with a view to its fuller explanation, we have already given, in speaking of Aben Ezra's opinion. (107) Many others are found in the course of the work: for instance, in chap. ii:12: "The Horims dwelt also in Seir beforetime; but the children of Esau succeeded them, when they had destroyed them from before them, and dwelt in their stead; as Israel did unto the land of his possession, which the Lord gave unto them." (108) This explains verses 3 and 4 of the same chapter, where it is stated that Mount Seir, which had come to the children of Esau for a possession, did not fall into their hands uninhabited; but that they invaded it, and turned out and destroyed the Horims, who formerly dwelt therein, even as the children of Israel had done unto the Canaanites after the death of Moses. (109) So, also, verses 6, 7, 8, 9, of the tenth chapter are inserted parenthetically among the words of Moses. Everyone must see that verse 8, which begins, "At that time the Lord separated the tribe of Levi," necessarily refers to verse 5, and not to the death of Aaron, which is only mentioned here by Ezra because Moses, in telling of the golden calf worshipped by the people, stated that he had prayed for Aaron. (110) He then explains that at the time at which Moses spoke, God had chosen for Himself the tribe of Levi in order that He may point out the reason for their election, and for the fact of their not sharing in the inheritance; after this digression, he resumes the thread of Moses' speech. (111) To these parentheses we must add the preface to the book, and all the passages in which Moses is spoken of in the third person, besides many which we cannot now distinguish, though, doubtless, they would have been plainly recognized by the writer's contemporaries. (112) If, I say, we were in possession of the book of the law as Moses wrote it, I do not doubt that we should find a great difference in the words of the precepts, the order in which they are given, and the reasons by which they are supported.
