4836. And Onan knew that the seed would not be his. That this signifies aversion and hatred, is evident from the representation of Onan, as being evil (n. 4823, 4824); and because not to give seed to one’s brother, or not to perform the duty of a husband’s brother, is not to will the good and truth of the church, and its continuation (n. 4834), therefore by these words is signified aversion and hatred; for evil is nothing else than aversion and hatred toward the good and truth of the church.

2848. Thy seed. That this signifies the spiritual who are saved in the good of faith by the Lord’s Divine Human, is evident from the signification of “seed,” as being the faith of charity (concerning which see n. 1025, 1447, 1610, 1941); or what is the same, those of the human race who are in the faith of charity, that is, who are spiritual. They are also called by the Lord the “seed,” and the “sons of the kingdom,” in Matthew:

He who soweth the good seed is the Son of man, but the seed are the sons of the kingdom (Matthew 13:37-38).
