Tosefta sobre Uktzim 3:16

And just as when they were in the desert, there were three camps -- the Camp of the Divine Presence (Shekhinah), the Camp of the Levites, and the Camp of Israel, so too it was in Jerusalem: From the entrance of Jerusalem until the entrance of the Temple Mount was the Camp of Israel. From the entrance of the Temple Mount until the Gates of Nicanor was the Camp of the Levites. From the Gates of Nicanor and within was the Camp of the Divine Presence, and this was [the area within] the hangings that was in the desert. But at the time that they journeyed ("וּבִשְׁעַת מַסָּעוֹת", see Bam. Rabbah 7:8), [that area] did not have any sanctity [as God's presence arose from the Ark as it traveled], and the people did not incur liability on account of impurity. (And how much is required to promote healing? We look at it as if it was the branch of a fig tree that was broken off, but was still attached by a little bark. If it could [continue] living from that [little bark], it is impure, and if not, it is pure. (Note: Per the commentators, the section "(And how...it is pure.)" is certainly misplaced. It appears to correspond to Oktzin 3:8.)
