588. Which can neither see nor hear nor walk, signifies in which and from which there is nothing of the understanding of truth or the perception of good, and thus nothing of spiritual life. This is evident from the signification of "to see," as being to understand truth (See above, n. 11, 260, 529); also from the signification of "to hear," as being to perceive and obey (See also above, n. 14, 249), and as being to have understanding to perceive, n. 529; also from the signification of "to walk," as being to live spiritually, and in reference to the Lord that it is life itself (See above, n. 97). From this it is clear that "not to see, to hear, or to walk," signifies that there is no understanding of truth, no perception of good, and thence no spiritual life; these are not in idols or from them, for "idols" signify the falsities of doctrine, of religion, and of worship, and such things are not in falsities, but in truths that are from good; in truths and from them is all understanding, all perception from the will of good, and consequently spiritual life. It is said "consequently," because spiritual life consists in the understanding of truth and in perception from the will of good; for truths are in the light of heaven, and this so much that the truths themselves give light in heaven, and this because the Divine truth proceeding from the Lord makes all light in the spiritual world, and that light gives all intelligence and wisdom to angels.

Now as truths themselves are of the light it follows that falsities are of no light, for they extinguish light, consequently falsities are called in the Word "darkness" (See above, n. 526); and as they are darkness, they are the shadow of spiritual death. But it is to be known that the falsities of evil constitute such darkness, not falsities that are not from evil. "To hear" signifies perception from the will of good, and thence obedience, because speech enters the ear at the same time with the sound, and the truths uttered enter the understanding and thence the thought, while sounds enter the will and thence the affection. That in the spiritual world sounds present and produce the affection which is of the will, and the words of the sound the thought which is of the understanding, may be seen in the work on Heaven and Hell 236, 241, and above n. 323. From this it can be seen why "to hear" and "to hearken" also signify to obey, and the "ear" and "hearing" obedience.

4603. 'The sons of Jacob were twelve' means a state in which all things were now present in the Divine Natural. This is clear from the representation of 'Jacob' as the Divine Natural, often dealt with already; and from the meaning of 'twelve' as all, and when used in reference to the sons of Jacob, or to the tribes named after these, as all aspects of truth and good, dealt with in 2089, 2129, 2130, 3272, 3858, 3913, 3939. The subject so far has been the way in which the Lord made his Natural within Him Divine, for 'Jacob' has represented the Natural; but now the subject becomes the joining of the Divine Natural to the Rational. This joining together is represented by Jacob's coming to Isaac, for 'Isaac' represents the Lord's Divine Rational. This explains why all the sons of Jacob are listed once again, since every aspect of truth and good had to be present within the Natural before it could be fully joined to the Rational. The reason for this particular listing of them is the service which the natural renders the rational as the receptacle for it. But one should recognize that Jacob's sons are now mentioned in a different order from before; the sons of Bilhah and Zilpah - Dan, Naphtali, Gad, and Asher - are mentioned last, though in actual fact these were born before Issachar, Zebulun, Joseph, and Benjamin. The reason for this difference is that at this point the subject is the order in which truths and goods exist within the Natural when this has been made Divine, for it is the state belonging to the subject under discussion that determines the order in which their names appear, see 3862, 3926, 3939.
