4239. 'Jacob sent messengers ahead of him to his brother Esau' means the first communication of that truth with celestial good. This is clear from the meaning of 'sending messengers' as communicating, and from the representation of 'Esau' as celestial good within the natural, dealt with in 3300, 3302, 3494, 3504, 3527, 3576, 3599, 3669. The subject at present, as stated above in 4234, is the joining of the Divine truth of the Natural, meant by 'Jacob', to the Divine good there, meant by 'Esau'. Consequently the enlightenment of the Natural by the Divine has been dealt with first, 4235, and now the first communication by the truth there, which is meant by the statement that 'Jacob sent messengers to his brother Esau'. Also, in the Word good and truth are referred to as 'brothers', see 367, 3303.

4116. 'And crossed the river' means a state in which a joining together takes place. This is clear from the meaning of 'the river', which in this case is the Euphrates, as a joining together, namely a joining to the Divine. The reason 'the river' has this meaning here is that it was the boundary separating the land of Canaan from that region, and all the boundaries of the land of Canaan were representative of and consequently meant spiritually that which came last and yet first - last because that was where it came to an end, and first because it was where it began. For all boundaries are such that they come last for those who are going out of the country but first for those who are coming in. Because Jacob was at that point coming in, that river was the first boundary that he crossed, and so means a joining together - in the highest sense a joining to the Divine; for 'the land of Canaan' in the internal sense means the Lord's heavenly kingdom, 1607, 3481, and in the highest sense the Lord's Divine Human, 3038, 3705. From all this one may see what is meant here by 'he crossed the river'. For all things in the land of Canaan were representative, with distances, positions, and boundaries determining their individual representations, see 1585, 3686; thus the rivers which served as boundaries, such as the river of Egypt, the river Euphrates, and the river Jordan, were representative, 1866.
