Exod. xx. enjoins the observance of the sabbath-day as a memorial of the repose of the Maker of heaven and earth on the sabbath of creation. Deut. v., the fourth commandment is enjoined because of the redemption of Israel from Egyptian bondage. Exod. xxxiv., a new version of the decalogue, differing in most respects from the one commonly received, is promulgated.* The first commandment is to worship no strange god; the second, to make no graven images; the third, to observe the feast of unleavened bread; the fourth, to deliver the first-born unto Jehovah; the fifth, to observe the sabbath, etc. * Compare De Wette's "Einleitung in das alte Testament" (Schrader's edition), p. 286, note 53. In Exod. xx. we read that the guilt of the fathers will be avenged upon the children down even to the third and fourth generation; in Deut. xxiv., the children shall not die for their fathers. Every one for his own sin shall die. In Deut. xxv. the marrying of a deceased brother's wife is under certain conditions enjoined as a duty. In Levit. xviii. it is unconditionally prohibited as a crime. Exod. xxxiii., Moses removes the tabernacle beyond the camp. Num. ii., the tabernacle rests in the very heart of the camp, with all the tribes of Israel grouped round about it, according to their standards and divisions. Num. xvi., the sons of Korah, the leader of the great Leviti-cal sedition, perish with their father. Num. xxvi., the sons of Korah do not perish.* Of the forty years which the Israelites are said to have dwelt in the desert, not more than two are covered by the events of the narrative. The remainder are wrapped in dense obscurity. There is, however, a significant fact which deserves mention in this connection. The death of Aaron marks, as it were, the close of Israel's journey. Now, while in Num. xxxiii. the death of the high-priest is described as occurring in the fortieth year, in Deut. x. it is actually referred to the second year of the Exodus.** * Num. xxvi. 11. Indeed, had the sons of Korah and every human being related to him perished, as Num. xvi. avers, how could we account for the fact that Korah's descendants filled high offices in the Temple at Jerusalem later on? The celebrated singer, Heman, himself was a lineal descendant of Korah. To the descendants of Korah also are ascribed the following Psalms: Ps. xlii., xliv.-xlix., lxxxiv., lxxxv., lxxxvii., lxxxviii. ** In connection with this subject it is of interest to compare Goethe's argument in the "Westoslicher Divan" on the duration of the desert journey. Here, as in so many other instances, the intuitive perception of the great poet anticipated the tardy results of subsequent investigation.
