Warren Buffett is universally admired for his wide-ranging wisdom. His sage insights on investing, as well as pithy quips on everything from leadership to marriage to Harley Davidson, have been quoted countless times.

Adding to the library of books mining the Berkshire Buddha’s wise investing principles is a new one that aims to draw parallels between Buffett’s philosophies and Jewish teachings.

In “Values Investing: An Omaha Rabbi Learns Torah From Warren Buffett,” Rabbi Jonathan Gross, who served as a rabbi of the only Orthodox synagogue in Omaha from 2004 to 2014, says he became a student of Warren Buffett, but not in the financial sense. “I have read his teachings looking for deeper meaning and I have found lessons about morality, ethics, and character development that are consistent with the values of the Torah and Jewish tradition.”

In 1996, the Berkshire chairman issued a booklet entitled “An Owner’s Manual” to Berkshire’s shareholders, the purpose of which was to explain the company’s broad economic principles of operation. “I set down 13 owner-related business principles that I thought would help new shareholders understand our managerial approach,” Buffett wrote. Coincidentally (or not), 13 is a meaningful number in Judaism: the great Jewish medieval philosopher Maimonides authored “The 13 Principles of Jewish Faith,” which boils the religion’s vast teachings down to 13 fundamental principles (e.g., the belief in the existence of God; the belief in God’s non-corporeality). “So the book basically wrote itself,” says Gross, 38.

Gross’s relationship with Buffett began with a chametz sale in 2012. During the eight-day Jewish holiday of Passover, observant Jews are required to rid their homes of all “chametz,” which includes anything made from major grains, like wheat, rye, barley, oats and spelt (more background here). This means they can’t eat it or own it. Most Jews do a thorough house cleaning and sell any chametz inadvertently left over to a non-Jew. So while he was working as rabbi of Beth Israel Synagogue in Omaha, Gross had an idea: Every year in his annual shareholder letter, Buffett invites people to reach out to him if they have investment ideas they want to share. In 2012, Gross wrote the Berkshire chairman a letter on behalf of him and his congregation, saying, before Passover we’re desperate to get rid of chametz so the price is low; a week later we’re craving bread, cookies and pasta, so the price would be high. It’s a risk-free arbitrage that’s been working for thousands of years.”

“The idea is simple. Buy low, sell high. A great short-term investment. I figured Warren Buffett should be able to relate to that,” Gross explained in his blog at the time. His idea was to sell Buffett the bulk food from the members of his synagogue who had gotten rid of it in preparation for Passover — and which he was going to donate to the local food bank — and ask Buffett “if he would kindly donate the chametz that he just acquired to the food bank.” Two days later Buffett’s secretary emailed Gross and invited him to the Berkshire office. “We sold our chametz to Warren Buffett. It was kind of a publicity thing for the local food bank. He would buy our chametz three times, and he would also donate [the food] and money to the food bank,” Gross says. “He was so generous with his time; he acted like I was the most important thing on his agenda.”
