Over the last 20 years, I’ve had the privilege of coordinating an invitation-only summit that brings together some of the world’s greatest rabbis and Torah scholars each summer.
The Global Yarchei Kallah, held at Camp Gan Israel in Parksville, New York, takes place over a long weekend each August. During this time, participants study together and discuss Jewish thought and law with high-caliber peers.
While their teachings are worth repeating, I’ve also found value in their behavior, mindset and habits, which can serve as lessons to others.
Here are nine of them:
1. They value time
When I called to invite Rabbi Chaim Shalom Deitsch, who heads the Tzemach Tzedek Kollel (advanced study institute) in Jerusalem, his wife said he would be home in 18 minutes. I later asked him how his wife knew precisely when he would be home. “Well,” he said, “services were going to conclude in 15 minutes, and it takes 3 minutes to walk home.” They calculate their time and honor it.

2. They take the long road — literally
Rabbi Leibel Shuchat, dean of Yeshiva Guedola of Venezuela, has lived in Caracas since 1985. Due to the country’s political turmoil, what was once a six-hour trip to New York has become a staggering 17-hour journey through Spain or Panama. But as anyone who studies Torah knows, acquiring it is a process and requires a long road — sometimes literally.
3. They respect themselves
Rabbi Chananya Yosef Eisenbach, the late dean of the Chabad Yeshiva in Bnei Brak, Israel, always carried himself with dignity. His clothing was simple yet impeccable, as the Talmud instructs (Shabbos 114a): “It is a disgrace for a Torah scholar to go out into the market with worn-out shoes ...” because one’s appearance reflects one’s status.
4. They don’t multitask
As he prepared to pray, I noticed Rabbi Yechiel Kalmenson, dean of Yeshiva Tomchei Tmimim in Burnoy, France, pausing for a moment of reflection. The Mishnah says (Berachot 5:1), “One should not stand up to pray except with a sense of reverence,” and he needed to enter that mindset. If it deserves one’s time, it deserves their full attention.
5. They practice disciplined flexibility
When Rabbi Sholom Ber Chaikin, posek (halachic authority) for Chabad of Northeast Ohio, studied Maimonides’ Mishneh Torah, he circled specific laws to revisit later so as not to impede reaching his daily study quota. Learning requires both discipline and flexibility.
6. They will talk with anyone
During the summit, Rabbi Avraham Shemtov, its founder and the Chairman of Agudas Chassidei Chabad International, naturally welcomed and conversed with its accomplished participants. Yet, if a staffer or youngster approached, he treated them with the same respect, recognizing that each person is created in the image of G-d (Genesis 1:27).
7. They recognize individuality
Rabbi Yisroel Friedman, the late dean of Beis Medrash Oholei Torah in Crown Heights, once arrived a few days early to the summit — to the delight of the camp’s staff members. When two of them asked to learn with him, he scheduled them at separate times. When I asked about it, he explained: “One is ‘fire,’ and one is ‘water.’ Each student has their abilities in learning, and combining them won’t work — for either of them. Each needs to be taught on their own level.”
8. They know their place
During a heated scholarly debate, I expected Rabbi Aizik Landa, the chief rabbi of Bnei Brak — a city renowned for its Torah scholarship — to chime in. Instead, he stayed silent, recognizing the topic wasn’t his area of expertise. Despite his vast knowledge, he understood that others were more immersed in that particular subject and respectfully yielded to them.
9. They teach by example
During their stay, the rabbis’ meals were served by young students who felt honored to serve their teachers. Yet Rabbi Zalman Wilschanski, the late dean of Yeshiva Tomchei Tmimim in Morristown, New Jersey, always left each of them a tip. Though not financially wealthy, he valued expressing gratitude, reminding us that kindness should always guide our actions. These are leaders of communities and rabbinical schools, revered sages and wise scholars.
Spend a few days with them — or a few minutes — and you’ll find there’s so much to relate to and to learn from them.
Tucson faith leaders, we would like to include your original sermon or scriptures of encouragement. Sermons must be written by the person submitting them, not borrowed from another source or writer. If you are a faith leader from any religion or denomination, please contact Sara Brown at sbbrown@tucson.com.
Faith leaders like Rabbi Joshua Franklin of the Jewish Center of the Hamptons in New York have begun to test the capabilities of ChatGPT and other AI chatbots for writing sermons. Many have found that it can in fact write a passably competent sermon, but cannot replicate the passion of actual preaching. "I told ChatGPT to write me a sermon and the voice of a rabbi of about a thousand words, about the Torah portion on the theme of intimacy and vulnerability," said Rabbi Franklin, who in late 2022 tested his congregation by giving a "plagiarized" sermon written by ChatGPT. "The goal was for them to figure out or try to understand or guess who wrote it," he said. "People thought that this content was generated by these really wise, smart, thoughtful individuals, where it had actually come from chatGPT. 100% of it." Rabbi Franklin said that he quickly realized this technology was no Google search engine, but had the ability to create AI content in a way he had never seen before. But he's concluded that rabbis and religious leaders are not obsolete. "ChatGPT has a lot of limitations," he said. "Eventually, it's going to be able to learn my style and my specific style. But giving a sermon and teaching a congregation is more about being in touch and being in relationship with them." Hershael York, a professor of Christian Preaching at The Southern Baptist Theological Seminary, has also experimented with ChatGPT and feels that AI is missing a soul. "You know, a mind without a soul is hardly capable of what I would consider true ministry," he said. As a professor, York and his colleagues are testing these chatbots to establish better rules around students using such technology in their work. "That was my primary engagement," he said. "And then as I did it, I also thought, okay, this could be a tool for what I would call lazy preachers." Although Rabbi Franklin said he would continue using ChatGPT as a learning and research tool regarding unfamiliar subjects, he also feels that because spirituality is often unexplainable by words, AI chatbots are "going to have major limits in the realm of faith and spirituality and religion."
