8063. In all thy border. That this signifies so far as the truth which is from good extends itself, is evident from the signification of “border,” as being the extension of truth from good; for all truth has its extension, which is sometimes manifested by a sphere; and because it has extension, it has its borders. The sphere of the extension of truth is according to the quality and the amount of good; for good is like flame, and truth is like light. The sphere of extension in the spiritual world is to the societies which are round about; and so far as the sphere extends into them, so far there is communication (see n. 6598-6613). In heaven everyone has intelligence and wisdom, and has happiness, according to the sphere of extension; that is, according to its amount and at the same time its quality. From all this it can be seen what is signified in the spiritual sense by “in all thy border,” here, that in good there must not be any falsity; for falsities are outside of the sphere, because they begin where truths leave off; whereas if they enter the sphere, they are appropriated. That they must not enter is signified by its being said “there shall no leavened thing, or leaven, be seen with thee in all thy border.”
