Dovid, Dovid, Dovid. What is that name all about? Do you know that Dovid is dominating the whole Teshuva business? How come Dovid steps in the whole Elul? He wanted: לְהוֹרוֹת תְּשׁוּבָה לַיָחִיד ע"ז ה א to show that a person can do Teshuva. Dovid is so special by us. And Elul stands for: אֲנִי לְדוֹדִי וְדוֹדִי לִי. I suspect that “Dovid” and "Dodi" are related.
** Dodi is a best friend. That's the way you have to deal with the Eibishter. יְדִיד נֶפֶשׁ אָב הָרַחֲמָן Yedid, Dodi, Dovid. Dovid is a friend. Dovid is warm. Dovid is Laibedik. He's Geshmak. You are comfortable with him. Everybody is comfortable with Dovid. He isn't “up there” in the sky. That's why Dovid sinned, and he was veeeeery full of worries, Sefer Tehillim is loaded with that stuff. He's one of us. With Dovid, we're all comfortable. He's the Lev of Klal Yisroel. (Rambam³).
