The phylacteries of the head correspond to: (Ex. 20:8) Remember, the phylacteries of the hand correspond to: (Deut. 5:12) Observe.
Just as carrying in the public domain is a desecration of the Sabbath, so is the misuse of the sign of the covenant its desecration, with a whore, who is ‘the alien domain’.
There is no positive or negative precept that is not
found in the Sabbath, and, because of this, the Sabbath is equal to the whole Torah.ciiiShemot Rabbah 25:12
