In case you haven't been following along, here's what has happened so far in
Numbers 16.
So, as you might expect, the people who had witnessed all this were pretty freaked out by now.
But on the morrow all the congregation of the children of Israel murmured against Moses and against Aaron, saying, Ye have killed the people of the LORD. (v.41)
Then "the glory of the Lord" appeared and God tells Moses he's going to kill everyone (again).
Behold ... the glory of the LORD appeared.
...
And the LORD spake unto Moses, saying, Get you up from among this congregation, that I may consume them as in a moment. (v.42-45a)
I think you can guess by now what Moses and Aaron did next.
They fell upon their faces. (v.45b)
Then Moses told Aaron to burn some incense to try to stop God from killing everyone. But God's plague had already started.
And Moses said unto Aaron, Take a censer, and put fire therein from off the altar, and put on incense, and go quickly unto the congregation, and make an atonement for them: for there is wrath gone out from the LORD; the plague is begun. (v.46)
But the incense burning worked, sort of, anyway. (Sometimes God will stop killing if you burn incense; sometimes
he'll burn you to death instead. He works in mysterious ways.) But not before 14,700 had died in the plague.
Now they that died in the plague were fourteen thousand and seven hundred, beside them that died about the matter of Korah. (v.49)
So in this chapter, God threatened to kill everyone twice, but settled for killing 14,962 instead in three separate killing events (a dozen or so buried alive, 250 burned to death, and 14,700 killed in a plague).
But don't complain about it or he'll kill you, too.
God's next killing: The massacre of the Aradites
