There's actually a book on this meter, . But the book doesn't seem to recognize the sevening, which is very prominent in David's meter. It matters, cuz millions of dollars have been WASTED due to folks misaccounting David's age at death; whole Bible is built around this, so if you miss his birth and death and years ruled, you'll get all your Bible dates in contradiction.
I don't know why the writer of the book in 1749 (!) didn't think to chart the meter for David's age, cuz it couldn't have escaped his notice: David uses FIVE 14s in a row, which is 70 (ding ding ding) then a 7 then another 7 to equal 84. It's all poetic, with soundplay, rhythm, so why didn't the guy notice David was writing when AGE 77 not age 70 as errant Josephus had long contended and dilatory scholars long accepted?
If we would just do our homework in BIBLE, then we'd save so much money, the poor would be fed and our sheep would get proper DOCTRINE so God could justify blessing US all to get even more money. Leviticus 26 and Deuteronomy 28, baby.
Here's my homework on the dateline: http://www.brainout.net/2Sam23.pdf
. It will be updated when I've time to do more work on it. See for yourself.
