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.
Isaiah 10:12-13
12
Therefore it will happen that, when the Lord has performed his whole work on Mount Zion and on Jerusalem, I will punish the fruit of the willful proud heart of the king of Assyria, and the insolence of his haughty looks.
13
For he has said, "By the strength of my hand I have done it, and by my wisdom; for I have understanding: and I have removed the boundaries of the peoples, and have robbed their treasures. Like a valiant man I have brought down their rulers.
