I too believe David & Abigail and their interactions and marriage are a Rapture Archetype.  I have posted thoughts on this…

Actually there is lots not only there but in the chapters preceding and following this which gives us insight.  It’s some of why I’m looking at December 22nd and Rosh Chodesh (new moon)

For more info on this go to:  www.tony4yhwh.com  and look under prophetic and then King David, Saul & Jonathan Rapture Archetypes
