With David taking a census, against God's orders (Exodus 30:12) and David begging God for forgiveness of his guilt (Samuel 24:10) then God giving David a choice of 3 punishments (Samuel 24:17) - the 3rd of which was chosen, a 3 year plague killing 70,000 of his people across the region.
So, assuming this fight does take place, don't come back and poll the forums as (Samuel 24:9) suggests that at this time there were 800,000 Israeli men alive - that means 8.75% of them died in that plague. Those aren't good odds for any of us here.
