Arcana Coelestia #4348
4348. 'Until he came right up to his brother' means a joining on the part of good that develops from truth, meant by 'Jacob'. This is clear from the meaning of 'coming right up to' as so as to join oneself; from the representation of Esau, to whom 'brother' refers here, as Divine Good within the natural, dealt with above in 4337; and from the representation of 'Jacob' as the good of truth, also dealt with above in 4337. The implications of all this have been explained immediately above in 4347.
