The wedding canopy of Mount Sinai[1]
…ברוך אתה יקוק מקדש עמו ישראל על ידי חופה וקידושין
…Blessed are You, Hashem, Who sanctifies His nation of Israel, through Chuppah and Kiddushin[2]
The blessing recited at every Jewish wedding, known as birkas erusin, ends with the idea that Hashem sanctifies His nation, through “Chuppah”, the wedding canopy, and “Kiddushin”, betrothal. How did Hashem sanctify us with Chuppah and Kiddushin? We could simply say that He sanctified us with the mitzvah of marriage through the process of Kiddushin, which is unique to Jews. However, some say[3] that this is a reference to Mattan Torah, the National Revelation at Sinai, where we received the Torah. The verse says that תורה צוה לנו משה מורשה קהילת יעקב, Moshe commanded us the Torah, an inheritance of the congregation of Yaakov[4]. Our Sages read[5] the word מורשה, inheritance, homiletically to be מאורסה, betrothed. Meaning, the Sinaitic experience was one of a marriage between the Jewish people and Hashem.
