Many thanks to Philip Pope for the permission to use his 2003 translation of the English King James Version Bible into Thai. Here's a link to the mission's website: www.thaipope.org
Arcana Coelestia #3243
3243. 'All these were the sons of Keturah' means as regards matters of doctrine and the worship that sprang from these. This is clear from the meaning of 'sons' as truths and matters of doctrine, dealt with in 489, 491, 533, 1147, 2623, and from the representation of 'Keturah' as Divine Spiritual Truth joined to Divine Spiritual Good, dealt with in 3236, 3237; thus things which belong to the Lord's spiritual kingdom are meant. And because the worship of that kingdom is in accordance with matters of doctrine, therefore the sons of Keturah mean matters of doctrine, and also the worship that sprang from these.
Arcana Coelestia #3237
3237. 'And her name was Keturah' means the essence of this Divine Truth. This is clear from the meaning of the word 'name' as the essential nature, and of 'calling by name' as knowing the essential nature, dealt with in 144, 145, 1754, 1896, 2009. Now because one does not speak of the nature of what is Divine but of the Esse of this, 'name' here means the essence, indeed the essence of Divine Truth - Divine Truth being meant here by 'the wife', to whom 'her' refers. For here 'the wife' means Divine Truth, see just above in 3236. From this it is evident what 'Keturah' in general embodies.
