EXOD453 It is a negative commandment to kill no living human being as Scripture says, You shall not murder [this verse]. If someone kills a human being deliberately, his execution should be by the sword [decapitation]. If he did not kill him with his own hand but only caused his death, he is not subject to execution by court verdict, but is punishable by death at Heaven's hands. If someone destroys even one living person in Jewry, it is as though he made a whole world perish. If someone closes a person's eyes at the departure of his life [instead of afterward] he thus sheds blood [by shortening the other's life, however briefly].
