Numbers 16:28-38

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.
36 Then the Lord spoke to Moses, saying:
37 Tell Eleazar son of Aaron the priest to take the censers out of the blaze; then scatter the fire far and wide.
38 For the censers of these sinners have become holy at the cost of their lives. Make them into hammered plates as a covering for the altar, for they presented them before the Lord and they became holy. Thus they shall be a sign to the Israelites.
