15
καὶ εἶπεν αὐτῷ κύριος ὁ θεός οὐχ οὕτως πᾶς ὁ ἀποκτείνας καιν ἑπτὰ ἐκδικούμενα παραλύσει καὶ ἔθετο κύριος ὁ θεὸς σημεῖον τῷ καιν τοῦ μὴ ἀνελεῖν αὐτὸν πάντα τὸν εὑρίσκοντα αὐτόν
Genesis 4:15
Arcana Coelestia #341
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.
