Arcana Coelestia #5940
5940. 'And go, get you to the land of Canaan' means their dwelling-place, that is to say, that of the truths of the Church within the natural. This is clear from the meaning of 'the land of Canaan' as the dwelling-place of those who belonged to the Church, dealt with in 3705, 3686, 4447, 4454, 4517, 5136, and so the dwelling-place of the truths of the Church together with good, for truths together with good constitute the Church.
Genesis 6:4
4
The Nephilim were in the earth in those days, and also after that, when God's sons came in to men's daughters. They bore children to them. Those were the mighty men who were of old, men of renown.
