900. 'And over the gates twelve angels, and names written thereon which are those of the twelve tribes of the sons of Israel' signifies the Divine truths and goods of heaven, which also are the Divine truths and goods of the Church, in those cognitions, and also guards lest anyone should enter unless he is in them by derivation from the Lord (ex Domino). By 'twelve angels' are here signified all the truths and goods of the Church; since by 'angels' is signified in the highest sense the Lord, in a general sense heaven by virtue of the angels, and in a particular sense the truths and goods of heaven from the Lord, as may be seen (n. 5, 170, 258, 344, 415, 465, 647, 648, 657, 718). Here are signified the truths and goods of heaven, because it follows on 'and names written thereon which are those of the twelve tribes of the sons of Israel', by which is signified all the truths and goods of the Church (n. 349). By 'over the gates' is signified in those cognitions, because 'over' in the Word signifies within. This is because that which is highest in successive order is the inmost in simultaneous order, and therefore the third heaven is called both the highest and the inmost heaven. This is why 'over the gates' signifies in the cognitions of truth. By 'names written thereon' is signified every quality thereof, thus also therein, for every quality is derived from the internals in external things. That by the same words are signified guards lest anyone should enter into the Church unless he is in those cognitions by derivation from the Lord, is plain, because the angels were seen standing over the gates, and also the names of the tribes of Israel were written upon them. It is said that the truths and goods of heaven and the Church are in the cognitions that are derived from the Word by which introduction into the Church is effected, because the cognitions of truth and good derived from the Word, when what is spiritual is in them out of heaven from the Lord, are not called cognitions but truths. But if what is spiritual is not in them out of heaven from the Lord, they are nothing but knowledges.
