Study Guide Kiddushin 56 Today's daf is dedicated in memory of those killed yesterday and today in the murderous attacks in Israel, for a refuah shleima to all those who were injured, and for the safe return of those taken captive. Today's daf is sponsored by Rivka Merzel in loving memory of Dr. Esther Erman. "Granny to all who knew her. At age 80 she started daf yomi and finished 2 complete cycles with siyums before she passed away on succot this year at age 97." The Gemara brings different contradictory sources relating to Rabbi Yehuda's opinion that a man who betroths a woman and knowingly uses maaser sheni, the betrothal is valid. In the end, the contradictions are resolved by assuming that the woman is knowledgeable in the halacha and will use the maaser money properly. Anything that is forbidden to benefit from can't be used to betroth a woman. The Mishna lists all those items and the Gemara outlines the sources for the prohibition for deriving benefit from each item.
