1413. 'To the land which I will cause you to see' means the spiritual and celestial things that were to be brought to view. This is clear from the meaning of 'a land', 662, 1066, and indeed from the meaning here of 'the land of Canaan' which represents the Lord's kingdom, as becomes clear from many places in the Word. For this reason the land of Canaan is called the Holy Land, and also the heavenly Canaan. And since it represented the Lord's kingdom, it also represented and meant the celestial and spiritual things that belong to the Lord's kingdom, and here those that belong to the Lord Himself.

2451. 'And all the inhabitants of the cities' means that all goods were severed from them so that they might possess nothing but evils. This is clear from the meaning of 'the inhabitants' when they are those of a city, as goods - as may be confirmed from many examples in the Word. This meaning is also evident from the fact that when 'a city' means truth, as has been shown, 'inhabitant' means good, for it is truth that good inhabits. But truth in which there is no good is like an empty or uninhabited city. That in addition to this all goods as well are separated from the evil so that they possess nothing but evils, see above in 2449.
