Arcana Coelestia #3234
3234. THE INTERNAL SENSE
Verse 1 And Abraham took another wife; and her name was Keturah.
'Abraham took another wife' means a further state which the Lord, whom Abraham represents, passed through - for 'Abraham and Sarah' represented the Lord as regards the Divine Celestial, 'Abraham and Keturah' the Lord as regards the Divine Spiritual, so that 'Abraham' here represents the Lord as regards Divine Spiritual Good, and his wife as regards Divine Truth allied to that Good. 'And her name was Keturah' means the essence of this Divine Truth.
Zechariah 14:17-18
17
It will be, that whoever of all the families of the earth doesn't go up to Jerusalem to worship the King, Yahweh of Armies, on them there will be no rain.
18
If the family of Egypt doesn't go up, and doesn't come, neither will it rain on them. This will be the plague with which Yahweh will strike the nations that don't go up to keep the feast of tents.
