6375. He binds his young ass unto the vine. That this signifies [conjunction through] truth in the natural for the external church, is evident from the signification of "binding," as being to be conjoined; from the signification of a "vine," as being the spiritual church (see n. 1069, 5113), here the external spiritual church, because by a "choice vine," presently mentioned, is signified the internal church; and from the signification of an "ass," as being truth in the natural (n. 2781). Hence it is plain that by "he binds to the vine his young ass" is signified conjunction through truth in the natural with the external church.
