Today’s daf has both human drama and a good lesson!
The daf today gets into the technical details of semikha—even down to how many hands you need. (Answer: two.) But what really caught my attention wasn’t the law—it was the moment between the rabbis.
Rabbi Elazar teaches a beautiful derivation about why semikha requires two hands… but he doesn’t quote his teacher, Reish Lakish. And Reish Lakish is not having it. He hears about it, gets upset, and starts firing off challenge after challenge—twenty-four verses to prove that the logic, as presented, doesn’t hold (Even though we, the readers, know it’s his argument!). Rabbi Elazar has no response. Total silence.
Only later, once things calm down, does Reish Lakish tell Rabbi Elazar how he should have defended his argument.
It’s such a human moment: the frustration, the intellectual sparring, the silence when someone gets called out.
But it’s also a really important lesson: Say things in the name of the person who taught them, B’shem Omro.
It’s not just about giving credit (though that matters). It’s also about context. About knowing where an idea comes from and how far it actually goes (like fact checking AI and google sources).
We live in a world where ideas travel fast, get repeated, reshaped, and often lose their origin entirely. The daf is reminding us that Torah—and really, wisdom more broadly—is not just about what is said, but who said it, and how it was meant.
Or, in Reish Lakish’s terms: If you’re going to teach it—teach it right.
Here’s the original exchange:
The mishna adds that the placing of hands is performed with two hands. The Gemara asks: From where are these matters derived? Reish Lakish said: As the verse states with regard to the Yom Kippur service: “And Aaron shall place both his hands [yadav] upon the head of the live goat” (Leviticus 16:21). The word yadav, meaning: His hands, is written without a second yod, and so if read without vowels it reads as: His hand. But it is also written “both,” which makes clear that the intention is that he must use both of his hands. This established a paradigm that in any place where it is stated in the Torah: His hand, there are here two hands, unless the verse explicitly specifies that there is only one. The Gemara relates: Rabbi Elazar went and stated this halakha in the study hall, but he did not say it in the name of Reish Lakish. Reish Lakish heard about this and became angry. He said to Rabbi Elazar: If it enters your mind that wherever it is written: His hand, the meaning is that there are actually two hands, then why do I ever need the Torah to write: His hands, his hands, i.e., yadav in the plural, which it does on numerous occasions? Reish Lakish raised objections against him from twenty-four occasions where the Torah writes: His hands, for example: “His own hands [yadav] shall bring the offerings of the Lord” (Leviticus 7:30); “his hands [yadav] shall contend for him, and You shall be a help against his adversaries” (Deuteronomy 33:7); “Guiding his hands [yadav] wittingly, for Manasseh was the firstborn” (Genesis 48:14). Rabbi Elazar was silent, as he had no response. After Reish Lakish had calmed down, he said to Rabbi Elazar: What is the reason that you did not say to me the following: When I established that paradigm, I was speaking only about the term: His hands [yadav], with regard to placing hands. But with regard to other halakhot, when the Torah says “his hand” the reference is to just one hand, and so when referring to two hands it must say “his hands.” The Gemara asks: But also with regard to placing hands it is written, concerning Moses’ ordination of Joshua: “And he placed his hands [yadav] upon him and gave him a charge” (Numbers 27:23), using the plural “his hands” [yadav] instead of: His hand [yado]. The Gemara clarifies that Reish Lakish meant that one could say: When I established that paradigm, I was speaking only about the term: His hands [yadav], with regard to placing hands on an animal offering. But in all other cases, if the intention is that there were two hands, the plural must be used
