9534. And thou shalt make unto it a closure of a handbreadth round about. That this signifies conjunction there with truth from the Divine, is evident from the signification of "a closure," as being the ultimate of the bounding, because it was outside the border, and thus it signifies conjunction with truth from the Divine. That this is signified by the "closure" cannot be known unless it is known how the case is with the extension and the bounding by the Lord of the sphere of good which compasses and thus protects heaven. (That the sphere of Divine good encompasses heaven and all the societies in heaven, and thus protects them from the breaking in of evils from hell, see above, n. 9490, 9492, 9498.)
[2] This Divine sphere extends even into the hells, and likewise guards them. Hence it is that the Lord reigns also in the hells, but with this difference, that the Divine sphere which encompasses and protects heaven is a sphere of Divine truth conjoined with Divine good; whereas the sphere which guards hell is a sphere of Divine truth separate from Divine good. That this is the sphere in hell, is because all who are there reject Divine good; thus the Lord's mercy. Such a sphere reigns in hell in the external form, but still in the internal form there reigns the sphere of Divine truth conjoined with Divine good; by which latter sphere those there are guarded lest one do evil to another beyond measure.
[3] From this it is evident that the sphere of Divine good in the external form ceases where heaven ceases; and that the sphere of Divine truth separate from Divine good begins where hell begins; and that in the interval between them there is conjunction, which is signified by "the closure of a handbreadth round about."
