Apocalypse Explained # 354
354. "Come and see," signifies attention and perception. This is evident from the signification of "coming" when anything is presented to be seen, as being to give attention; for in a spiritual sense, "to come" means to draw near with the sight, thus to give attention; all attention also is a presence of the sight in the object. It is evident also from the signification of "to see," as being perception, for "to see" in the Word signifies to understand (See above, n. 11, 260); here it signifies to perceive, because this was out of the inmost heaven, since what comes out of the inmost heaven is perceived, but what comes out of the middle heaven is understood, for the reason that the inmost heaven is in the good of love, but the middle heaven is in the truths therefrom, and all perception is from good, and all understanding is from truths. (On this see above, n. 307; what perception is, see in The Doctrine of the New Jerusalem 140.)
Arcana Coelestia # 5410
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.
