Arcana Coelestia # 2585
2585. Verse 18 For Jehovah had completely closed every womb of Abimelech's house because of the matter of Sarah, Abraham's wife.
'For Jehovah had completely closed every womb of Abimelech's house' means sterility of doctrine. 'Because of the matter of Sarah' means through the rational if it had joined itself. 'Abraham's wife' means, in order that spiritual truth might be joined to celestial good.
Isaiah 66:7-9
7
"Before she travailed, she brought forth; before her pain came, she delivered a son.
8
Who has heard such a thing? who has seen such things? Shall a land be born in one day? shall a nation be brought forth at once? for as soon as Zion travailed, she brought forth her children.
9
Shall I bring to the birth, and not cause to bring forth?" says Yahweh: "shall I who cause to bring forth shut [the womb]?" says your God.
