Arcana Coelestia # 8666
8666. 'And they came into the tent' means the holiness of union. This is clear from the meaning of 'the tent' as the holiness of love, dealt with in 414, 1102, 2145, 2152, 4128, and so the holiness of union, since love consists in union. Consequently 'coming into the tent' means being united by holy love. The subject in the present verse is the union of Divine Good with God's truth; and since all union is brought about by the flowing of the one into the other, which results in perception, then by a bringing towards and placing in contact of one with the other, and after that a joining together of them, the influx and resulting perception is described first, 8660, then the bringing of one towards the other, 8662, and also the placing one in contact with the other, 8663, after that the joining together, 8664, and finally the union through love.
Arcana Coelestia # 1101
1101. 'May God enlarge Japheth' means the enlightenment of that Church. In the literal sense 'enlarging' means extending boundaries, but in the internal sense it means being enlightened. Indeed enlightenment is an extension so to speak of the boundaries of wisdom and intelligence, as in Isaiah,
Enlarge the place of your tent, and let the curtains of your habitations be stretched out. Isaiah 54:2.
This stands for enlightenment in spiritual things. The member of the external Church is 'enlarged' when he receives instruction in truths and goods of faith. And because charity is present in him he is by this means confirmed more and more. Also, the more instruction he receives the more the cloud is dispersed in the understanding part of his mind in which charity and conscience are present.
