[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.
