Technically God killed those ten people, Satan was just like "idk man do you think that guy really worships you, even when shit's not going his way?"

Those two million are the people killed by God in Bible who were numbered. There is also a lot of them not given count, for example just the Flood would killed 30 million if it happened around the estimated time.

Yeah it's accurate unless you count Revelation and then both rack up pretty decent kill counts.

Or if your Gnostic and are all "akhtually, that's the demiurge sweaty"
