6033. And fell upon his necks. That this signifies conjunction, is evident from the signification of “falling upon the necks,” as being conjunction close and intimate (see n. 5926). That “to fall upon the necks” signifies conjunction is because the neck joins together the head and the body, and by the “head” are signified the interiors, and by the “body” the exteriors. Hence the “neck” denotes the conjunction of the interiors with the exteriors, and thus the communication of the interiors with the exteriors, and also of celestial things with spiritual (see n. 3542, 5320, 5328), which communication is by virtue of conjunction also signified by these same words, for “Joseph” is the internal, and “Israel” is relatively the external.

5320. And put a necklace of gold upon his neck. That this signifies a significative of the conjunction of interior things with exterior, effected by good, is evident from the signification of the “neck,” as being the influx and also the communication of higher things with lower things, or what is the same, of interior things with exterior (see n. 3542); hence a “necklace,” because it encircles the neck, is a significative of the conjunction of these things. A “necklace of gold” signifies conjunction through good, or effected by good, because “gold” signifies good (n. 113, 1551, 1552). A mark of the conjunction of interior with exterior truth is signified by a “necklace upon the throat” in Ezekiel:
I decked thee with ornament, and I put bracelets upon thy hands, and a necklace upon thy throat (Ezekiel 16:11).
