Numbers 16:30; Numbers 16:33

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."

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.
