Numbers 16:25-35

25 So Moses got up and went to Dathan and Abiram; the elders of Israel followed him.
26 He said to the congregation, "Turn away from the tents of these wicked men, and touch nothing of theirs, or you will be swept away for all their sins."
27 So they got away from the dwellings of Korah, Dathan, and Abiram; and Dathan and Abiram came out and stood at the entrance of their tents, together with their wives, their children, and their little ones.
28 And Moses said, "This is how you shall know that the Lord has sent me to do all these works; it has not been of my own accord:
29 If these people die a natural death, or if a natural fate comes on them, then the Lord has not sent me.
30 But if the Lord creates something new, and the ground opens its mouth and swallows them up, with all that belongs to them, and they go down alive into Sheol, then you shall know that these men have despised the Lord."
31 As soon as he finished speaking all these words, the ground under them was split apart.
32 The earth opened its mouth and swallowed them up, along with their households—everyone who belonged to Korah and all their goods.
33 So they with all that belonged to them went down alive into Sheol; the earth closed over them, and they perished from the midst of the assembly.
34 All Israel around them fled at their outcry, for they said, "The earth will swallow us too!"
35 And fire came out from the Lord and consumed the two hundred fifty men offering the incense.
