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.
Arcana Coelestia #1897
1897. Verse 2. And Sarai said to Abram, Behold, now, Jehovah has prevented me from bearing; go in now to my servant-girl; perhaps I shall be built up from her; and Abram hearkened to Sarai's voice.
'Sarai said to Abram' means that it was so perceived by Him. 'Behold, now, Jehovah has prevented me from bearing' means the state prior to the birth of the Interior or Divine Rational Man. 'Go in now to my servant-girl' means a joining to the more exterior man. 'Perhaps I shall be built up from her' means the possibility of the rational being born in that way. 'And Abram hearkened to Sarai's voice' means it could not have been achieved in any other way.
