And when the ‘other gods’ see, the differentiation on the Sabbath of everything, they have no permission to approach. It is this that is written: (Num. 1:51)... and the stranger (zar) who approaches will die, because: (Ex. 31:14) It is holy for you, its desecrators∞me-ḥalaleha will surely die... And because of this, it is stated in scripture: (Ex. 31:13)... My Sabbaths you shall keep... etc.
And with these additions, the Shekhinah is called ‘the additional service’ (musaph) of the Sabbath. And when all the levels of the mundane are distanced from Her, and there is no alien domain on the Sabbath, to enter between the blessed Holy One and His Shekhinah, She is called His ‘holiness’. And when they bless Her with the blessing over food, She is called His ‘blessing’. And in both-of-them, She is His unity, His bride. At that time: She, ‘the Sabbath, is equal to the whole Torah’.xcixShemot Rabbah 25:12
