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.
Arcana Coelestia#6680
6680. 'And they kept the boys alive' means that the truths, being the truths of good, were preserved. This is clear from the meaning of 'keeping alive' as preserving; and from the meaning of the sons, who are called 'the boys' here, as truths, dealt with above in 6676. The sons are called 'the boys' here because the good of innocence is meant by 'boys', 430, 2782, 5236, and therefore 'the boys' here are truths which are the truths of good.
