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 #492
492. Verse 5 And all the days of Man in which he lived were nine hundred and thirty years; and he died.
Here, as previously, 'days' and 'years' mean periods of time and states. 'He died' means that this kind of perception existed no more.
