Deuteronomy (n.)youdaoicibaDictYouDict[Deuteronomy 词源字典]
5th book of the Pentateuch, late 14c., from Late Latin Deuteronomium, from Greek Deuteronomion, literally "second law," from deuteros "second" (see deuterium) + nomos "law" (see numismatics). A mistranslation of Hebrew mishneh hattorah hazzoth "a copy of this law" [Deut. xvii:18]. The book is a repetition, with comments, of the Decalogue and most of the laws of Exodus. The title was translated literally into Old English as æfteræ, literally "after-law."[Deuteronomy etymology, Deuteronomy origin, 英语词源]
