5822. If our youngest brother be with us, then will we go down. That this signifies unless there be with them a conjoining intermediate, is evident from the representation of Benjamin, who here is the "youngest brother," as being a conjoining intermediate (see n. 5411, 5413, 5443, 5639, 5668). In regard to this, that Benjamin represents the intermediate between the celestial of the spiritual, or internal good, which is "Joseph," and truths in the natural, which are the "ten sons of Jacob," and also that he represents new truth (as in n. 5804, 5806, 5809), the case is this. An intermediate in order to be an intermediate must derive something from each, namely from the internal and from the external; otherwise it is not a conjoining intermediate. The intermediate which Benjamin represents derives from the external or natural that it is new truth there; for the new truth which he represents is in the natural, because it is from the spiritual good from the natural, which his father represents as Israel (n. 5686, 5689); but the intermediate derives this by influx from the internal which is represented by Joseph. Thus it derives something from each. This is the reason why Benjamin represents a conjoining intermediate, and also new truth-new truth when with his father, a conjoining intermediate when with Joseph. This is a secret which cannot be more clearly set forth; and it cannot be understood except by those who are in the thought that there is with man an internal and an external distinct from each other; and who are also in the affection of knowing truths. These are enlightened in respect to the intellectual part by the light of heaven, so that they see what others do not see, thus also this secret.
