Because they had supernatural powers, when one reads the original bible, the burning bush translates to; he burned all 613 onto a disc. Oh, and that wasn't two stone tablets they were written on, he was holding his laptop sideways.;-)
:) That is a jewish philosophers compilation not the Decalogue or ten commandments. The canonized Decalogue(ten commandments) can be found in these books Exodus 20:2–17 Deuteronomy 5:6–21.
Most of the Rabbi's commandments that you linked to are for Jewish ritual or day to day living. Rituals for the temporary cleansing of sins whether through willful intent or sins of omission. The Rabbi is still waiting for their messiah to signal the coming of the age of Messiah, for them the Messiah is not an individual so much as an age when the rituals will no longer be required because sin and evil cease to exist.
The Decalogue is on a different spiritual level as given to Moses, It was not given as a bar for the people to live above ...it is impossible, Christians believe it is to communicate to Gods people how far they had slipped from Gods original intent for them ( see Augustines doctrine of original sin). It sets the stage for the resolution of sin and death and the restoration of Gods people with the coming Messiah. Man must recognize his own failings and choose the salvation offered through a sacrifice that was different from all of the ritual sacrifices in the book of Leviticus, the rituals in Leviticus could not attain a lasting absolution, lasting absolution required a sacrifice that is perfect, the coming Messiah.
All that to say you misinterpreted the Rabbi's list.
