The word _Chattath_, in the sense of sin offering, occurs in Exod. xxix., xxx., and many times in Leviticus and Numbers, and six times in Ezekiel. Otherwise in the Old Testament it is barely mentioned, except in the post-exilic Books of Chronicles (2 Chron. xxix. 24) and Ezra (viii. 25).[345] It is not mentioned in any other historic book; nor in any prophet except Ezekiel. Again, as we have seen, the Day of Atonement leaves not a trace in any of the earlier historic records of Scripture, and is found only in the authorities above mentioned. Through all the rest of Scripture the scape-goat is unmentioned, and Azazel is ignored. Dr. Kalisch goes so far as to say that "there is conclusive evidence to prove that the Day of Atonement was instituted considerably more than a thousand years after the death of Moses and Aaron.[346] For even in Ezekiel, who wrote B.C. 574, there is no Day of Atonement on the tenth day of the seventh month, but on the first and seventh of the first month (Abib, Nisan)." He thinks it utterly impossible that, had it existed in his time, Ezekiel could have blotted out the holiest day of the year, and substituted two of his own arbitrary choice.[347] The rites, moreover, which he describes differ wholly from those laid down in Leviticus. Even in Nehemiah there is no notice of the Day of Atonement, though a day was observed on the twenty-fourth of the month. Hence this learned writer infers that even in B.C. 440 the Great Day of Atonement was not yet recognised, and that the pagan element of sending the scape-goat to Azazel, the demon of the wilderness, proves the late date of the ceremony. It is interesting to observe how utterly the sacrificial priestly system, in the abuses which not only became involved in it, but seemed to be almost inseparable from it, is condemned by the loftier spiritual intuition which belongs to phases of revelation higher than the external and the typical.
