Sugar Stars for Parshat Lech Lecha

In this week’s parsha, Hashem tells Avraham and Sarah to pack their stuff and go to Eretz Canaan. Hashem promises Avraham that his descendants will be as many as the sand and stars. This week we’ll be making sugar cookies in the shape of stars—so make sure to have a star cookie cutter.


Rabbi Dr. Moshe Dovid Tendler, zt”l

On the day following Simchat Torah, the most joyous celebration in the Jewish calendar, the world heard the devastating news that one of Jewry’s greatest 20th-century talmidei chachamim, who combined his exceptional Torah scholarship with a stellar career in microbiology, had passed from this world.


‘Synthetic’ Biology of the Torah Variety

Over the recent Sukkot holiday I read an article titled “Halakhic Issues Related to Synthetic Biology” by Rabbi Dr. Moshe D. Tendler, zt”l, (co-authored with John Loike and Ira Bedzow and published in the most recent issue of Hakirah). Synthetic biology is a new interdisciplinary area involving the application of


A Hesped for Rabbi Moshe Dovid Tendler, zt”l

We are here today to mourn the loss and reflect on the life and legacy of Rabbi Moshe Dovid Tendler, a senior rosh yeshiva at Rabbi Isaac Elchanan Theological Seminary, professor of biology and former chair of the biology department in Yeshiva College, the Rabbi Isaac and Bella Tendler Professor of Jewish Medical Ethics.


A Student’s Memories of Rav Tendler

In Rav Tendlers’s long teaching career, I was among his last students. I didn’t know Rav Tendler for long but the zman I spent in his shiur four years ago was very impactful. He said a lot of things that had a strong influence on me. Here’s a few of them:

Glatt kosher: Rav Tendler was very strong about glatt kosher being a chumra and how it was terrible

Beyond Nature

Excerpted from the original, which can be found at rabbisacks.org, along with footnotes.

Are we naturally good or naturally bad? On this, great minds have argued for a very long time indeed. In Judaism, according to the Sages, this was the argument between the angels when God consulted them as


Lessons From the Haftarah of Parshat Chukat: How to Respond to Anti-Israeli Slander

This article was first published in TABC’s Kol Torah and is reprinted here with the permission of the author.

Stunning! Just stunning! The parallels between the haftarah for Parshat Chukat and our current situation in Israel send shudders down our spines! The lessons that emerge are crucial and


The Sin of Indifference

Parshat Noach

Years ago, in my shul in the Bronx, New York, my father, a”h, would stand by the bimah during the Torah reading and, as gabbai, he would recite the MiSheberach for the sick. Generally, he was prepared with a list of names of those who were ill, but, invariably, there were those who


Caring for Others

In this week’s parsha, a relatively famous Gemara mentioned by Rashi prompts additional thought and consideration.

Commenting on the Torah’s description of Noach as a righteous man “b’dorotav,” “in his generation,” Rashi cites the Gemara Sanhedrin 108a, which notes two ways to understand


Dating in Sura and Pumbedita

The first Mishna (Rosh Hashanah 2a) states that the first of Nisan is the Rosh Hashanah for kings, and Rav Chisda (a third-generation Amora, head of Sura academy, lived 217-309 CE) explains that the practical import is for the dating of Jewish legal contracts.
