5410. 'To buy grain from Egypt' means to make the good of truth its own through factual knowledge. This is clear from the meaning of 'buying' as making one's own, dealt with in 4397, 5374, 5406; from the meaning of 'grain' as the good of truth, dealt with in 5295; and from the meaning of 'Egypt' as factual knowledge, dealt with above in 5402.
