(“Until” the execution of the defendant)
(Q) Why not even after the execution? (Kal V’chomer)
(While it’s true, we do not learn it from the verse that the saducees brought; but, maybe we can learn it from a kal v’achomer)
(A) Punishment is never administered through A kal v’ chomer.
This principle is derived from the laws of illicit relationships. (verse mentions punishment for relationship with half sisters and still mentions sisters as well. Every punishment and prohibition must be explicit)
“If a man shall take his sister, daughter of his father or daughter of his mother,” (Vayikra 20,17)
“ he has uncovered the nakedness of his sister,” (Vayikra 20,17)
