Time Travel – Kiddushin Tractate Version
Question
Hello Rabbi,
I’m learning folio 19b in tractate Kiddushin with a study partner. A very strong question came up among the learners (namely, me and my study partner): can kiddushin move backward along the timeline? (Like kiddushin that take effect “from now, after thirty days,” which take effect retroactively.)
For example: would “Behold, you are betrothed to me after thirty days, from yesterday” take effect?
Answer
No. Only from the time the act of kiddushin is performed.
