Numbers 16:35

32 and the earth opened its mouth, and swallowed them up, and their households, and all the men who appertained to Korah, and all their goods.

33 So they, and all that appertained to them, went down alive into Sheol: and the earth closed on them, and they perished from among the assembly.

34 All Israel that were round about them fled at the cry of them; for they said, Lest the earth swallow us up.

35 Fire came forth from Yahweh, and devoured the two hundred fifty men who offered the incense.

36 Yahweh spoke to Moses, saying,

37 Speak to Eleazar the son of Aaron the priest, that he take up the censers out of the burning, and scatter you the fire yonder; for they are holy,

38 even the censers of these sinners against their own lives; and let them be made beaten plates for a covering of the altar: for they offered them before Yahweh; therefore they are holy; and they shall be a sign to the children of Israel.
