2067. 'And I will bless him' means the multiplication of this, namely of the Rational meant by 'a son'. This is clear from the meaning of 'being blessed' as being enriched with everything good and true, dealt with just above in 2065.

2065. That 'I will bless her' means the multiplication of truth is clear from the meaning of 'being blessed' as being enriched with everything good and true, dealt with in Volume One, in 981, 1096, 1420, 1422. Since here it is Sarah to whom the statement that God would bless her refers, the enrichment or multiplication of truth is meant, for, as shown already, 'Sarah' represents and means truth that is joined to good, which is intellectual truth. Such truth, and the multiplication of it, is the subject here. As to what intellectual truth is, see what has been said already in 1904.
