That the Holy Blessed One practices social distancing, from where do we learn it (מנא לן)? As it is written (דכתיב): “The Lord spoke to Moses after the death of the two sons of Aaron who died when they drew too close to the presence of the Lord. And the Lord said to Moses: “Tell your brother Aaron that he is not to come at will into the Shrine behind the curtain, in front of the ark cover, lest he die, for I appear in the cloud over the cover.” (Leviticus 16:1-2) And from where that God wears a mask? As it is written (דכתיב): “He shall put the incense on the fire before the Lord, so that the cloud from the incense screens the cover that is over the [Ark of the] Pact, lest he die.” (Leviticus 16:13)
