8876. 'Visiting the iniquity of the fathers on the sons' means the consequent propagation of falsity from evil. This is clear from the meaning of 'visiting the iniquity of the fathers' as the propagation of evils, the reason why 'visiting' means propagating being that the subject is the state of those who completely reject the Divine, therefore who are receptive no longer of good but of evil, and constantly so since evil is constantly increasing with such people, which is the propagation of it (for the meaning of 'father' as good and in the contrary sense as evil, see 3703, 5902, 6050, 7833, 7834); and from the meaning of 'the sons' as truths, dealt with in 1147, 2623, 3373, and therefore in the contrary sense as falsities In the proximate sense 'visiting the iniquity of the fathers on the sons' does not mean that sons pay the penalty for the iniquity of their fathers, for that is contrary to the Divine, Deuteronomy 24:16. Rather the meaning in that sense is that evil increases with the fathers and so is passed on by heredity to their children, and that consequently the evil mounts up over successive generations, 2910, 3701, 4317, 8550, 8551. In the spiritual sense however 'the fathers' does not mean fathers but evils, and 'the sons' does not mean sons but falsities; therefore those words mean the constant propagation of falsity from evil.

'And it was cloud and darkness [for the former]' means that the falsity arising from evil on the one side was intensified; 'and it lit up the night [for the latter]' means that the truth springing from good on the other side grew brighter. This is clear from the meaning of 'cloud and darkness' as the intensification of falsity arising from evil ('cloud' means falsity, see 1043, 1047, 8137, 8138, as also does 'darkness', 1839, 1860, 4418, 4531, 7688, 7711); and from the meaning of 'lighting up the night' as the brightening of truth springing from good. 'A pillar of fire by night' means a state of dimmed truth, moderated by enlightenment from good, 8108.

[2] With regard to the pillar, that it brought darkness to the Egyptians but light among the children of Israel, the situation is that the Lord's presence, which is meant here by 'the pillar', is heavenly light itself. From this heaven derives its light, a light that is a thousand times brighter than light in the world at midday. Yet the same light turns into thick darkness among the evil, even though they may be in actual light; and it turns to even thicker darkness as the falsity arising from evil among them grows in intensity. The reason for this is that God's truth coming from the Lord appears before angels' eyes as light. But it cannot appear as light to those steeped in falsities arising from evil, only as thick darkness, since falsity is the opposite of truth and snuffs it out. This is why the pillar, which was the Lord's presence, brought cloud and darkness to the Egyptians, 'the Egyptians' meaning those steeped in falsities arising from evil, and lit up the night among the children of Israel, 'the children of Israel' meaning those guided by truth springing from good. The Lord appears to each person in a way suited to the kind of person he is, see 1861(end), 6832.
