9373. Come up unto Jehovah. That this signifies conjunction with the Lord, is evident from the signification of “coming up,” as being to be raised toward interior things (see n. 3084, 4539, 4969, 5406, 5817, 6007), consequently also to be conjoined (n. 8760). That it denotes conjunction with the Lord, is because by “Jehovah” in the Word is meant the the Lord, (n. 1343, 1736, 1793, 2004, 2005, 2018, 2025, 2921, 3023, 3035, 5663, 6280, 6303, 6905, 8274, 8864, 9315). A secret which also lies hidden in the internal sense of these words, is that the sons of Jacob, over whom Moses was the head, were not called and chosen; but they themselves insisted that Divine worship should be instituted among them (according to wh at has been said in n. 4290, 4293); and therefore it is here said, “and He said unto Moses, Come up unto Jehovah,” as if not Jehovah, but another, had said that he should come up. For the same reason in what follows it is said that “the people should not go up” (verse 2); and that “Jehovah sent not His hand unto the sons of Israel who were set apart” (verse 11); and that “the appearance of the glory of Jehovah was like devouring fire on the top of the mountain in the eyes of the sons of Israel” (verse 17); and lastly that Moses, being called the seventh day, “entered into the midst of the cloud.” For by “the cloud” is meant the Word in the letter (n. 5922, 6343, 6752, 6832, 8106, 8443, 8781); and with the sons of Jacob the Word was separated from its internal sense, because they were in external worship without internal, as can be clearly seen from the fact that now, as before, they said, “all the words which Jehovah hath spoken we will do” (verse 3); and yet scarcely forty days afterward they worshiped a golden calf instead of Jehovah; which shows that this was hidden in their hearts while they were saying with their lips that they would serve Jehovah alone. But nevertheless those who are meant by “the called and the chosen” are those who are in internal worship, and who from internal worship are in external; that is, those who are in love to and faith in the Lord, and from this in love toward the neighbor.

“Washing” in the Bible represents purification - unsurprisingly! Washing dirt from the skin symbolizes using true ideas from the Lord to remove evil desires and false ideas from our minds. This is the reason that washing was such an integral part of ritual; cleaning the body to perform physical acts of worship - something with no actual spiritual value - is symbolic of repenting our evils and falsities as part of worshiping the Lord.

6775. 'And the priest of Midian had seven daughters' means holy things belonging to that Church. This is clear from the meaning of 'a priest's daughters' as things that belong to the Church, for 'a daughter' means a Church, see 2362, 3963, 6729, and 'a priest' the good of love, 1728, 3670, 6148, so that 'a priest's daughters' means a Church so far as its good is concerned; from the meaning of 'Midian' as people who are guided by the truths that go with simple good, dealt with just above in 6773; and from the meaning of 'seven' as that which is holy, dealt with in 395, 433, 716, 881, 5265, 5268. Thus 'the priest of Midian had seven daughters' means holy things belonging to the Church among those who are guided by the truths that go with simple good. The people said to be governed by simple good are those who keep up the external practices of the Church and who in simplicity take the Word literally, each one believing it according to his own understanding. They also lead lives that accord with what they believe, and so are governed by good, depending on the nature of that good, which is determined by the truths that guide them. That good brings an internal dimension of the Church to these people, but because they are not guided by truths of a more internal kind, the good entering in becomes something general and accordingly vague, since spiritual light is unable to fall on particular aspects and thereby illuminate things distinctly. The kind of people spoken of here have heaven granted to them in the next life as determined by the nature of their good, which depends on their truths. People such as these are meant here by 'Midian'; but properly speaking they are those outside the Church who lead a good life in keeping with their type of religion.
