Numbers 16:30-35

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 And as he finished speaking all these words, the ground under them split asunder;
32 and the earth opened its mouth and swallowed them up, with their households and all the men that belonged to Korah and all their goods.
33 So they and all that belonged to them went down alive into Sheol; and the earth closed over them, and they perished from the midst of the assembly.
34 And all Israel that were round about them fled at their cry; for they said, "Lest the earth swallow us up!"
35 And fire came forth from the LORD, and consumed the two hundred and fifty men offering the incense.
