They find beauty in the commentaries by sages of words in the scriptures. Every grammatical nuance has meanings for which there are references and related stories, some humorous. The extent of knowledge is often encyclopedic and the works and scholarship of major schools of thought are discussed with the same joy as new moves in a champion chess game by masters.
But they could be talking instead, (or also), about the quality of the food in a new glatt-kosher restaurant or the coming marriage of some offspring!
