4271. 'And he took them and made them pass over the river, and made all that he had pass over' means a further instillation. This is clear from what has been stated immediately above, for he made not only wives, servant-girls, and sons pass over but also herds and flocks, and so everything he had, into the land of Canaan in which he met Esau. And since the subject in the internal sense is the joining together of truth and good within the natural, 'passing over the river' means nothing else than the first instillation, and here where the same words are repeated, with the addition of the phrase about his making all that he had pass over, a further instillation is meant.
