3504.'So that my soul may bless you' means allying it to its own life, consequently life that corresponds to the rational. This is clear from the meaning of 'being blessed' as being endowed with celestial and spiritual good, dealt with in 981, 1731, 2846, 3017, 3406. For the good of early childhood and consequently the good of life, which is the same as the good of the natural, and which is represented by 'Esau', is not spiritual good, for the good of early childhood is devoid of knowledge and intelligence, and so of wisdom. The good of early childhood becomes spiritual good through the implantation of truth, and so through regeneration, see 1616, 1802, 2280, 2290, 2291, 2299, 2304, 2305, 2307, 3494 (end). This is how the correspondence between rational things and natural is effected, and so how the allying of the natural man to the life of the rational is effected. This allying to its own life is what is meant by 'my soul may bless you'.

2846. 'I will certainly bless you' means fruitfulness by virtue of the affection for truth. This is clear from the meaning of 'being blessed' as being enriched with celestial and spiritual good, dealt with in 981, 1096, 1420, 1422 - here, being enriched with good that is the product of faith, or what amounts to the same, with the affection for truth, for those who are spiritual are the subject. In this verse where Jehovah says to Abraham, 'I will certainly bless you', Abraham represents the Lord as regards the Divine Human, as he has done already in this chapter. The Lord Himself was not able to be blessed as He is Blessing itself; but the verb 'to be blessed' is used when, as His love desires, the number of those who are being saved is abounding, and therefore in the internal sense it is these that are meant here, as is clear also from the things that follow next. The expression 'fruitfulness' is employed here because it is said in reference to affection, whereas the expression 'multiplying', as in what follows, has reference to truths derived from that affection.
