3380. And in thy seed shall all the nations of the earth be blessed. That this signifies all who are in good, both within and without the church, is evident from the signification of “being blessed,” as being to be made fruitful in good and to be multiplied in truths (see n. 981, 1422, 1731, 2846, 3140); from the signification of “seed,” as being the goods and truths which are from the the Lord, (n. 3373); and from the signification of the “nations of the earth,” as being all who are in good (n. 1259, 1260, 1416, 1849). Thus by “all the nations of the earth being blessed in thy seed,” is signified that through the good and truth which are from the Lord all are saved who live in mutual charity, whether they are within the church or without it. (That the Gentiles who are without the church and who are in good are equally saved, may be seen above, n. 593, 932, 1032, 1059, 1327-1328, 2049, 2051, 2284, 2589-2604, 2861, 2986, 3263)

2846. That in blessing I will bless thee. That this signifies fructification from the affection of truth, is evident from the signification of “being blessed,” as meaning to be enriched with celestial and spiritual good (see n. 981, 1096, 1420, 1422); here, to be made fruitful from the good of faith, or what is the same, from the affection of truth, because the spiritual are treated of. It is here said by Jehovah to Abraham, “in blessing I will bless thee,” and by Abraham is represented the Lord as to His Divine Human, as before in this chapter; and yet the Lord Himself could not be blessed, because He is blessing itself; but He is said to be blessed, when in accordance with His love those abound who are saved; and therefore in the internal sense these are here signified, as is also evident from what immediately follows. Fructification is here spoken of, because this is predicated of affection; but multiplication, as next follows, is predicated of the truths which are therefrom.
