In response to Clay's 2/13 post about 527 at http://www.fivedoves.com/letters/feb2007/clay213.htm it is interesting to note that the number 527 is also tied to Isaac's birth year.  Pastor Riley previously pointed out that Abraham, Isaac's father, was born in 2008 which would mean Abraham's son Isaac was born in 2108 since Abraham was 100 yrs. old at the time of Isaac's birth.  The year Isaac was born 2108 = 4 x 527.  I just thought I would point it out.
 
It is also interesting to note that the Greek word Harpazo which is Greek word #726  for "catch up" (rapture) in Strong's Concordance has a gematria of 989.  When 726 is added to 989, it equals 1715 which is 5 x 343.  Hebrew word #343 in Strong's Concordance means calamity or destruction.  So could some terrible calamity happen on the day of the Rapture when believers are caught up to heaven?
