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.

2018. That 'I will establish My covenant between Me and you' means union is clear from the meaning of 'a covenant' as union, dealt with already in 665, 666, 1023, 1038. This union has been dealt with above in this chapter and in other places before that, where it has been shown that Jehovah who is the speaker here was within Him, because He was one with Him from the very start of conception and birth. For He was indeed conceived from Jehovah, and therefore His Internal was Jehovah. And in 1999 this has been illustrated by the similarity that exists with man; that is to say, his soul is one with his body, or his internal one with his external, even though they are quite distinct and separate from each other. Sometimes they are so distinct that one is in conflict with the other, as normally happens in times of temptation when the internal reproaches the external and wishes to cast out the evil that is within the external; nevertheless they are joined together or are one since soul and body both belong to the same person. Take for example a person whose thought is something other than what is expressed in his looks, speech, and actions. In his case that which is more interior is at variance with that which is external; yet the two make one, for the thought is just as much part of that person as the external is to which looks, speech, and actions belong. Union exists however when the latter - looks, speech, and action - are in agreement with the thought. So much for these remarks added by way of illustration.
