May the Humra Di’R. Zeira be Relaxed in Cases of Halakhic Infertility?

Rabbi Aryeh Klapper (Posted on June 18, 2018)
From the Lindenbaum Center for Halakhic Studies

Introduction “Halakhic infertility” occurs when observance of hilkhot niddah results in a woman ovulating only during the days that wife and husband are forbidden to be physically intimate. These situations result from post-biblical stringencies that lengthen the time of prohibition. This article discusses whether a couple may cease observing one such stringency, the humra di’R.…

Rema’s Understanding of Reheating Liquid Foods on Shabbat

Rabbi David Fried (Posted on May 23, 2018)
From the Lindenbaum Center for Halakhic Studies

Introduction The mishnah in Shabbat 145b states: “Anything that has been prepared in hot water prior to Shabbat, may be immersed in hot water on Shabbat.” From here we learn the principle of ein bishul ahar bishul (one does not violate the Biblical prohibition of cooking when reheating food that has already been cooked).…

Is There Anything I May Do on Shabbat to Prepare for Yom Tov?

Rabbi Avram Schwartz (Posted on May 16, 2018)
From the Lindenbaum Center for Halakhic Studies

  This weekend, we will celebrate another marathon holiday – Shabbat followed by Shavuot. Shavuot, occurring later in spring, presents its own challenges of time: each day of the holiday, as with all yamim tovim, does not begin until dark, but as preparing for one day of the holiday on the previous one (or on Shabbat for Yom Tov) is forbidden, any preparations not done before the holiday may not begin until very late in the evening.…

May a Husband Give His Wife Supportive Touch During Childbirth? – Part 2

by Rabbi Dov Linzer Posted on April 26, 2018

May a husband hold his wife’s hand or give her a massage during childbirth, according to halakhah?  We began to answer this question last week and came to the following interim conclusions: A pregnant woman is not considered to be in niddah until either she experiences uterine bleeding (distinct from mere stains), or until a limb of the baby emerges from the womb. …

May a Husband Give His Wife Supportive Touch During Childbirth?  – Part 1

by Rabbi Dov Linzer Posted on April 19, 2018

QUESTION:  I am nine months pregnant, and my husband and I have been doing Lamaze classes to prepare for the birth of our baby.  Part of the Lamaze method includes pressure massage and massage of the abdomen.  I have been told, though, that it is forbidden by halakhah for my husband to do this because I will be in niddah at that time. …

May Kohanim Become Doctors – Part 2

by Rabbi Dov Linzer Posted on March 22, 2018

Two weeks ago we began to explore the question of whether kohanim may become doctors according to halakhah.   We noted that three halakhic arguments could be advanced to question the applicability of this prohibition to the case at hand: (1) Kohanim nowadays are only presumed (hazakha) to be kohanim and might only have the status of doubtful (safek) kohanim; (2) If we are all presumed to be tamei nowadays, then, according to Ra’avad, kohanim do not violate a Biblical prohibition by becoming tamei again by a corpse; (3) According to Yereim, it is not a violation for kohanim to become tamei by the corpse of a non-Jew. …

May A Single Man Fulfill The Mitzvah Of Pru U’rvu (procreation)?

Rabbanit Dr. Michal Tikochinsky (Posted on March 11, 2018)
From the Lindenbaum Center for Halakhic Studies

To read this teshuva in hebrew click here: Introduction Until the last generation, marriage and reproduction always went together. The only legitimate way of producing children was in the framework of marriage since non-marital sexual relationships are halakhically forbidden or, minimally, strongly discouraged.[1] In our generation, technologies have evolved that enable reproduction outside the context of marriage that do not cross these lines.…
