All Israel that were round about them fled at the cry of them: for they said, Lest the earth swallow us up also. Numbers 16.34But they were safe, at least for the moment, because God had his mind on other victims.
Remember Moses' original plan for dealing with Korah's rebellion? He told him and his associates to burn incense before the Lord and let God choose who is holy.
This do; Take you censers, Korah, and all his company; And put fire therein, and put incense in them before the LORD to morrow: and it shall be that the man whom the LORD doth choose, he shall be holy. 16.6-7But then God came up with the burying alive thing and the censer-swinging, prayer contest was put on hold.
In the meantime, 250 of Korah's followers did as Moses asked and burned some incense. So God burned them all alive to teach them a lesson or something. (If you do what he says he'll burn you to death?)
There came out a fire from the LORD, and consumed the two hundred and fifty men that offered incense. 16.35At least I don't have to guess the number of victims this time.
God's next killing: 14,700 killed for complaining about God's killings
