Arcana Coelestia #2848
2848. 'Your seed' means spiritual people who, having that good within them that springs from faith, are saved by the Lord's Divine Human. This is clear from the meaning of 'seed' as faith that is the expression of charity, dealt with in 1025, 1447, 1610, 1941, or what amounts to the same, those members of the human race who possess faith that is the expression of charity, that is, who are spiritual people. They are also called by the Lord 'the seed' and 'the sons of the kingdom', in Matthew,
He who sows the good seed is the Son of Man, but the seed are the sons of the kingdom. Matthew 13:37-38.
Jeremiah 23:5-8
5
Behold, the days come, says Yahweh, that I will raise to David a righteous Branch, and he shall reign as king and deal wisely, and shall execute justice and righteousness in the land.
6
In his days Judah shall be saved, and Israel shall dwell safely; and this is his name by which he shall be called: Yahweh our righteousness.
7
Therefore, behold, the days come, says Yahweh, that they shall no more say, As Yahweh lives, who brought up the children of Israel out of the land of Egypt;
8
but, As Yahweh lives, who brought up and who led the seed of the house of Israel out of the north country, and from all the countries where I had driven them. They shall dwell in their own land.
