The ten commandments

the long version

"In this lively and provocative book, Michael Coogan guides readers into the ancient past to examine the iconic Ten Commandments, also known as the Decalogue. How, among all the laws reportedly given on Mount Sinai, did the Ten Commandments become "the" Ten Commandments? When did that happen? There are several versions of the Decalogue in the Old Testament, so how have different groups determined which is the most authoritative? Why were different versions created?"--book jacket.
