341. Verse 2 And she bore again, his brother Abel. And Abel was a Shepherd of the flock, and Cain was a tiller of the ground.

The second born of the Church is charity, which is meant by 'Abel' and by 'brother. A shepherd of the flock' means one who practices good flowing from charity, while 'a tiller of the ground' means someone who, devoid of charity, acts from faith separated from love, which is not faith at all.

7009. 'And it will happen, that he will be for you as a mouth' means the truth contained in doctrinal teachings, which also goes forth from the Lord in an indirect way. This is clear from the representation of Aaron, who 'will be for Moses as a mouth', as doctrinal teachings, dealt with in 6998; and from the meaning of 'being for Moses as a mouth' as the utterance or declaration of it, dealt with in 6987. The reason why the words of explanation are 'the truth contained in doctrinal teachings, which also goes forth from the Lord in an indirect way' is that the truth contained in doctrinal teachings, which 'Aaron' represents, is the kind of truth that can be heard and discerned by angels and by men. Such truth is what goes forth in an indirect way from the Lord. But the kind of truth that is represented by 'Moses' goes forth directly from the Lord, and cannot be heard or discerned by men, nor even by angels, see 6982, 6985, 6996, 7004.
