Im looking for the talmud section Libbre David 37

"Libbre David" is not a traditional tractate of the Talmud. It's possible that you might be referring to a different text or perhaps an interpretation of Talmudic material. The Talmud consists of the Mishnah and the Gemara, divided into various sections and tractates. If you meant a specific passage or idea related to a Talmudic discussion, could you please clarify your request? This would help me provide a more accurate response regarding what you're looking for.
