3987. And now when shall I also be doing for mine own house? That this signifies that now its own good shall be made fruitful therefrom, is evident from the signification of a "house," as being good (see n. 2233, 2234, 3128, 3652); and here of "my house," as being the good signified by "Jacob." That "to do for this house" signifies that the good therefrom is to be made fruitful, is manifest from the subject being the fructification of good and the multiplication of truth; for by "Joseph," the last born, this fructification is signified (n. 3965, 3969, 3971); and by the "flock" that Jacob procured for himself by means of Laban's flock, as now follows, this signification is described. That good is not fructified nor truth multiplied until the conjunction of the external man with the internal has been effected, may be seen from the fact that it is of the interior man to will good to another, and thereby to think good; but of the external man to do good, and thereby to teach good. Unless doing good is conjoined with willing good, and teaching good with thinking good, there is no good in the man; for the evil can will evil and do good, and also think evil and teach good, as everybody can know. Hypocrites and profane persons are in this study and art more than others, so much so indeed that they can palm themselves off as angels of light, when yet they are devils within; from all which it is evident that good can be made fruitful with no one, unless doing good is conjoined with willing good, and teaching good with thinking good; that is, unless the external man is conjoined with the internal.
