Keeping the Sabbath holy is not a moral imperative, it is a rule of Hebrew ritual.No they are all morals however they all boil down to one basic moral imperative, thou shall not steal. Everyone of them is about not taking what rightly belongs to others.
An injunction against stealing and murder is more like a criminal code.
Being able to restrain yourself from murdering and stealing is the absolute lowest possible moral bar to clear. That bar is set so low it barely clears the ground.
