In Maseches Kiddushin, wherein we learn about the various laws of getting halachically betrothed and various aspects of marriage, there is a very interesting halacha we learn. Before getting any further into this, keep in mind that this was a very different time, and slavery as a concept was different than it is now. There’s a specific halacha that prohibits a Jewish slave-owner from treating a Jewish slave any worse than himself, and Rambam highly encourages treating gentile slaves with the same kindness.
It says there in a discussion about redeeming slaves and umos (Jewish maidservants) by paying off their remaining years of servitude, that if a girl is already halachically betrothed she cannot be sold into servitude. The way it is stated there is that if she has already been sold into ishus (marriage), then she cannot be sold into shifchus (maidservant status). There is another halacha taught there that once a man has designated her as betrothed to him through placing his garment on her, she can then no longer be sold as a maidservant.
What we can learn from this set of halochos is a great Sod in terms of our relationship with Hashem. Klal Yisroel is always described as being the wife or bride of Hashem. We see all the time though how difficult things have been for Jews throughout history, and how difficult things may become in the future. There is a concept that Hashem follows the Torah and keeps halacha, which means that even a detail like this He keeps also, so to speak. Even if Klal Yisroel is experiencing incredibly difficult times, even subjugation to reshoim, what is important is to remember is that we are still wedded to Hashem and He will never sell us into true slavery. Every day we have a mitzvah to remember that He took us out of Mitzrayim, and from this we have to remember that we are in truth free from the powers of the Klippa, but the Erev Rav and Sitra Achra want us to forget this.
The advice to transcend this to some degree is to place His garment upon yourself, and designate yourself as betrothed to Hashem. You can take this literally and be more careful about wearing tzitzis, which would literally be a garment of Hashem. The better approach is more metaphysical, that is to sit and learn Torah and clothe yourself with Hashem’s mitzvos, by always trying to fulfill various mitzvos throughout the day. When we do this, we can break through the veils the Erev Rav tries to blind us with and come to true d’veikus.
