3504. That my soul may bless thee. That this signifies adjunction to his life, and consequently life corresponding to the rational, is evident from the signification of “being blessed,” as being to be gifted with celestial and spiritual good (n. 981, 1731, 2846, 3017, 3406); for the good of infancy and of life thence, which is the same as the good of the natural, and which is represented by Esau, is not spiritual good-the good of infancy being devoid of knowledge and intelligence, and thus of wisdom. The good of infancy becomes spiritual good through the implanting of truth, thus through regeneration (n. 1616, 1802, 2280, 2290, 2291, 2299, 2304, 2306-2307, 3494); hence comes the correspondence between rational and natural things, consequently the adjunction of the natural man to the life of the rational; this adjunction to its life being what is meant by “my soul blessing thee.”

3406. And Jehovah blessed him. That this signifies in respect to the good of love therein, is evident from the signification of “being blessed,” as being to be enriched with all celestial and spiritual good (n. 981, 1731, 2846); thus to be “blessed by Jehovah” is to be enriched with celestial good, which is of love, for Jehovah is the very being of love or of good (n. 1735); and therefore where good is treated of, “Jehovah” is named; but where truth is treated of, “God” is named (n. 2586, 2769).
