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.
Joshua 11:16-17
16
So Joshua took all that land, the hills, and all the south country, and all the land of Goshen, and the valley, and the plain, and the mountain of Israel, and the valley of the same;
17
Even from the mount Halak, that goeth up to Seir, even unto Baal-gad in the valley of Lebanon under mount Hermon: and all their kings he took, and smote them, and slew them.
