Arcana Coelestia #6283
6283. 'And in them will my name be called' means that in them the essential nature of the good of spiritual truth from the natural will be present. This is clear from the meaning of 'one's name being called in another' as the essential nature of one in the other, dealt with in 1754, 1896, 2009, 3421; and from the representation of 'Israel' as the good of spiritual truth from the natural, dealt with above in 6277. And since they had within them Israel's essential nature they were accepted among the rest of Jacob's sons and became tribes, one the tribe of Manasseh, the other the tribe of Ephraim. Along with the rest - though excluding the tribe of Levi because it became the priesthood - they made up the twelve tribes when inheritances were allotted to them, as described in Joshua and also Ezekiel 48.
Jeremiah 49:1-3
1
Of the children of Ammon. Thus says Yahweh: Has Israel no sons? has he no heir? why then does Malcam possess Gad, and his people well in its cities?
2
Therefore, behold, the days come, says Yahweh, that I will cause an alarm of war to be heard against Rabbah of the children of Ammon; and it shall become a desolate heap, and her daughters shall be burned with fire: then shall Israel possess those who did possess him, says Yahweh.
3
Wail, Heshbon, for Ai is laid waste; cry, you daughters of Rabbah, clothe yourself in sackcloth: lament, and run back and forth among the fences; for Malcam shall go into captivity, his priests and his princes together.
