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.
Isaiah 58:14
14
then you shall delight yourself in Yahweh; and I will make you to ride on the high places of the earth; and I will feed you with the heritage of Jacob your father:" for the mouth of Yahweh has spoken it.
