Arcana Coelestia #567
567. The whole of that region is called the area of the Church where people who have been instructed in the doctrine of true faith are situated, as the land of Canaan was when the Jewish Church was there, and as Europe is where the Christian Church is today. Lands or regions outside of them are not areas of the Church, or 'the face of the ground'. Where the Church existed prior to the Flood becomes clear also from the lands which were encompassed by the rivers flowing out of the garden of Eden, rivers which are also frequently described in the Word as the boundaries to the land of Canaan. Where it was situated prior to the Flood is also clear from what follows that description, for example, from the reference to the Nephilim being in the land, whose presence then in the land of Canaan is clear from the statement in Numbers 13:33 that the sons of Anak came from the Nephilim.
Isaiah 30:23-24
23
He will give the rain for your seed, with which you will sow the ground; and bread of the increase of the ground will be rich and plentiful. In that day, your livestock will feed in large pastures.
24
The oxen likewise and the young donkeys that till the ground will eat savory provender, which has been winnowed with the shovel and with the fork.
