Arcana Coelestia #1018
1018. The reason why it is here said again, “Be ye fruitful, and multiply” as in the first verse (Genesis 9:1) of the chapter, is that here is the conclusion, and that all things will go well, and will be fruitful and multiply, if men shun what is signified by eating blood and by shedding blood, that is, if they do not extinguish charity by hatreds and profanations.
Luke 6:32
32
If you love those who love you, what credit is that to you? For even sinners love those who love them.
