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.

To build something generally means to put together a variety of simpler pieces to make a useful and more complex structure, as to build a house out of wood or bricks, and it is commonly used this way in the Word. In the land of Shinar men wished to build a tower, and in the new testament Jesus advised that a wise man should build his house on a rock. But in a representative sense the meaning is to build a mental and spiritual structure, like the doctrine of a church or the individual concepts of spiritual reality in a single mind. The building materials are representative also. The tower of Babel was built of brick, which is man-made rock, or representatively, man-made "truths", that is"truths" not from God but ideas of spiritual reality thought out by men. The house that the wise man would build was founded on a natural or "God-made" rock, which means a truth from the Word.
