Apocalypse Explained #383
383. His name was Death, and Hell followed with him. That this signifies eternal damnation, appears from the signification of name, as denoting the quality of a thing (concerning which see above, n. 102, 148); here, the quality of the Word, [with those] who are in evils and the falsities thence; from the signification of death as denoting damnation (concerning which also see above, n. 186), for spiritual death is nothing else; from the signification of hell, as denoting evil and the falsity thence, because in these and from these hell exists. Furthermore, by hell is signified the same as by death, namely, damnation, but because both are here mentioned, and thus [hell] is distinguished from Death, by hell is signified eternal damnation; for those who come into hell remain there to eternity; therefore it is also said, "and Hell followed with him," to follow with him signifying to abide therein, namely, in damnation to eternity. From these considerations it is evident that by "his name was Death, and Hell followed with him," is signified eternal damnation.
Arcana Coelestia #7269
7269. 'And Aaron your brother will be your prophet' means doctrinal teachings derived from it. This is clear from the meaning of 'prophet' as the truth contained in doctrinal teachings, thus teachings derived from the Word, dealt with in 2534. For more about the representation of 'Aaron' as the teachings of the Church or teachings derived from the Word which present what is good and true, see 6998, 7009, 7089. Since 'prophet' means doctrinal teachings, its meaning in a more precise and limited sense is, in accordance with what has been stated immediately above at the end of 7268, a teacher.
