At the risk of being view as JW, I think the 144k, I'll call the perfect square whole number thingy because I'm not expert on numerical terminology, are representative of the "raptured," and so their 'sealing' before judgment commences. So I think these are us, all of us, no waiting for any more Jews to come in or anything. IOW, the last trump speaks to the (announcement the beginning of the new (year) arriving (and the books determining individuals' fate for the coming year are opened in order to be written in or erased from). And that 'there is silence in heaven for the space of half an hour,' cause me wonder if this is likened to the 10 day grace period until the great trump is sounded which announces the final seal of the book, if you're written in, you're in, if not, woah. Thereafter, the only one's inflicted or dying are those found not written in the book of like or rather that received the mark of the beast.
And I reconcile, "And he causes all (categories of people), man, woman, and child, bond, free, rich, poor, no exceptions... unless God forbid it of course... but this happens before the impervious sealing of the whole (perfect) body of which those killed in former manner are raised whole and impervious along with those that remain being changed into the same state.
