While wandering around aimlessly in the desert, Moses suddenly got really angry about how people were fucking and decided to put an end to it.

He suddenly decided that among a lot of other things, incest was no longer allowed, nor was male-on-male fucking, nor was sacrificing your grandchildren to this other god named Malek or Moloch.

He also decided that the penalty for most of these crimes should be that people just throw rocks at you until you die. So... murder was back on the table!
