Why is Hashem's name missing in Shir Hashirim? The haggadah is so specific in mentioning Hashem's name over and over and instead leaves out Moshe's name (except one time). I'm wondering why then Hashem's name is missing in the megillah we read on the same holiday? I've heard many answers in regards to the purim megillah and how it had to be a nes nistar vs the Haggadah wants to make it clear its a nes nigleh and all from Hashem. But what is the reason Hashem's name is missing in Shir Hashirim?
Rabbi Binyamin Shmueli says on Hidabroot that the reason Hashem's name is not found in Shir Hashirim is since it is a song of love between Hashem and the Jewish nation it is written in a way that people will not be jealous of this special relationship.
כל שיר השירים כתוב בצורת סוד וברמיזה ולכן גם שם ה' לא כתוב. זהו שיר אהבה של הקב"ה לעם ישראל ולהיפך והשיר נכתב בצורה עדינה שלא יקנאו בנו אחרים.
