Why Koheles Spoke Before a Crowd
Shlomo said his words before a gathering because the Shechinah rests on Israel when they stand together in love.
Chazal say Shlomo was called Koheles because he said all his words before an assembly. Why should that matter? The Lehavas David brings from his great-grandfather's Divrei Binah a saying of R' Dovid of Lelov: when two Jews join together, they are like two letters yud, which together write Hashem's Name. Every new Torah insight, the Divrei Binah explains, comes from combinations of the Torah's letters, and in Shlomo's days the combination rising from the Jewish people was complete, for there was great love among them; every man of Yehudah and Yisroel sat under his vine and his fig tree. Shlomo knew how to join all of Israel's powers together. He spoke before the gathered people because he wanted the Shechinah to rest among them as he taught, and the Shechinah rests on Israel through unity.

Shlomo taught before a crowd because the Shechinah rests where Jews come together in love. This week, turn one solitary moment of Torah into a shared one. Invite a friend, a neighbor or one of your children to learn a few lines with you, even for ten minutes. At the Shabbos table, ask someone else to share a thought before you share yours. Notice how a single verse feels different when two people hold it together.
