Arcana Coelestia #4919
4919. 'And it happened as she was giving birth' means a bringing forth. This is clear from the meaning of 'giving birth' as acknowledging in faith and action, dealt with in 3905, 3915, 3919. And because that which is acknowledged in faith and action is something that is brought forth, 'giving birth' also means a bringing forth - a bringing forth of good and truth, the essentials of the Church.
Arcana Coelestia #3919
3919. 'And Bilhah conceived, and bore Jacob a son' means reception and acknowledgement. This is clear from the meaning of 'conceiving' as reception, and from the meaning of 'bearing' as acknowledgement, dealt with in 3860, 3868, 3905, 3911. For in the spiritual sense conceptions and births are receptions of truth from good, and consequent acknowledgements.
