After we wrap the tefillin strap around the middle finger and hand, we say, “I will betroth you to me forever, and I will betroth you to Me with righteousnes, justice, kindness, and mercy. I will betroth you to Me with fidelity, and you shall know Hashem”. This verse from Hoshea 2:21-22 is talking about our relationship with Hashem. Wow, that’s quite a powerful list of attributes describing how Hashem relates to his faithful people. Wearing tefillin is a clear demonstration of our faith. Day after day, we never miss our oppurtunity to wear the boxes that remind of how Hashem took us out of Egypt, and how we are obligated to serve Him with all of our abilities. Wearing tefillin is part of the process of becoming betrothed to Hashem, and in turn meriting Hashem’s everlasting promise of treating us with righteousness, justice, kindness, and fidelity. The verse concludes by granting us the greatest gift of all: knowledge of G-d!
