Arcana Coelestia #6360
6360. 'I will divide them in Jacob' means that they are to be banished from the natural man. This is clear from the meaning of 'dividing' or cutting off as separation and removal from truth and good, dealt with in 4424, thus a banishment; and from the representation of 'Jacob' as the natural or external man, dealt with in 3305, 3576, 4286, 4292, 4570, 6236.
Luke 1:31-33
31
Behold, you will conceive in your womb, and bring forth a son, and will call his name 'Jesus.'
32
He will be great, and will be called the Son of the Most High. The Lord God will give him the throne of his father, David,
33
and he will reign over the house of Jacob forever. There will be no end to his Kingdom."
