3937. 'Zilpah, Leah's servant-girl, bore a second son to Jacob' means acknowledgement of a second - a second general truth. This is clear from the meaning of 'bearing' as acknowledgement, dealt with above in 3911, 3915, 3919; from the meaning of 'a servant-girl' as an affirmative means that serves to join the external man to the internal, dealt with in 3913, 3917; from the meaning of 'son' as truth, in this case a general truth, dealt with above in 3926; and from the representation of 'Jacob', and also 'Leah' as well as 'Zilpah', dealt with above. These considerations show what the internal sense of these words is, namely the acknowledgement of the second general truth which serves as the means to join the external man to the internal.

3926. 'A second son to Jacob' means a second general truth. This is clear from the meaning of 'son' as truth, dealt with in 489, 491, 533, 1147, a general truth being meant at this point, as is clear from what has been stated and shown above concerning the twelve sons of Jacob and concerning the twelve tribes named after them; that is to say, the general aspects of the Church, and consequently the general aspects of faith and love, or of truth and good, are meant and represented by those sons. They also mean in the contrary sense every general aspect of that which is not faith or love, that is, every aspect of falsity and evil, as will be evident from what is said further on.
