BSD The Kiddushin that never started. If a man tells two sisters: “One of you is mekudeshes to me” (and both sisters are willing partners), such Kiddushin cannot be consummated, as each sister is either his wife or his “erva” (i.e. wife’s sister who is forbidden to him). Is such “unconsummatable” Kiddushin considered Kiddushin at all (and the sisters would have to receive a get) or is it just one big nothing to begin with (nd no get is required)? This is a machlokes between the famous Abayey and Rava. Watch it all here.
