Arcana Coelestia #3925
3925. 'Bilhah, Rachel's servant-girl, conceived again and bore' means reception and acknowledgement. This is clear from the meaning of 'conceiving' as reception, and from the meaning of 'bearing' as acknowledgement, dealt with above in 3919; and also from the meaning of 'a servant-girl' as a subservient means, also dealt with above, in 3913, 3917. For here the second subservient general means by which the internal man is joined to the external is the subject.
Arcana Coelestia #3917
3917. 'And she gave him Bilhah her servant-girl as his wife' means that a link with the affirmative means was established. This is clear from the representation of 'Bilhah', and from the meaning of 'a servant-girl' as an affirmative means, dealt with just above in 3913; and from the meaning of 'giving as his wife' as establishing a link.
