6027. And he sent Judah before him unto Joseph. That this signifies the communication of the good of the church with the internal celestial, is evident from the representation of Judah, as being the good of the church (see n. 5583, 5603, 5782, 5794, 5833); and from the representation of Joseph, as being the internal celestial (n. 5869, 5877); that "to send before him" denotes to communicate, is plain. The reason why Judah was sent, and not another, was that there might be signified the communication of good with good, which is immediate; namely, the communication of external good, which Judah represents, with internal good, which Joseph represents. For the good which is of love to the Lord and of charity toward the neighbor flows in from the Lord through the internal into the external; and so much is received in the external as there is of good there. But if in the man's external there is only the truth of faith, and not good, then the influx of good from the Lord through the internal is not received in the external; for immediate communication with truth is not possible, but only mediate communication through good. This is the reason why no other than Judah was sent by Jacob unto Joseph.
