Kottke linked to a nice list of mass people killin' in the bible. And by nice, I mean of course appalling. But in the same way I was appalled when the Sentinels under the control of Sebastian Shaw murdered many members of the X Men. That is, I read this stuff and take it with a grain of salt. Anyway, here's some good ol' fashion biblical smiting!
4. Elijah (and God) burned to death 102 men. 2 Kings 1:10-12 5. David killed 200 Philistines to purchase his first wife with their foreskins. 1 Samuel 18:25-27, BT 6. Abishai killed 300 men with a spear. 2 Samuel 23:18, 1 Chronicles 11:20, BT
Rest of the list here.
