9458. 'Speak to the children of Israel' means the representative Church. This is clear from the representation of 'the children of Israel' as the Church, in particular the spiritual Church, dealt with in 8805, 9340, but at this point the representative Church, since the kinds of objects that represented the holy things of the Church and of heaven are the subject, such as the ark, the mercy-seat, the cherubs, the table on which the loaves of the Presence were laid, the lampstand, and further on the tabernacle, Aaron's garments, and the altar and sacrifices, all of which were representative. The reason why the spiritual Church is meant by 'the children of Israel' is that it was represented by them. However no actual representative Church could be established among that people, only a representative of a Church, see 4281, 4288, 4311, 4444, 4500, 6304, 7048, 9320.
Arcana Coelestia#1529
1529. It is very well known in heaven, but not so well known in the world of spirits, where so great a light comes from, namely from the Lord. And what is astonishing, the Lord appears to celestial angels in the third heaven as the Sun, but to spiritual angels as the Moon. There is no other source of light. But the intensity of the light angels experience depends on how celestial and spiritual they are, and the nature of the light depends on the nature of these qualities. Thus the Lord's celestial and spiritual itself shows itself before angels' external vision by means of the light.
