Numbers 16:32
KJV
And the earth opened her mouth, and swallowed them up, and their houses, and all the men that appertained unto Korah, and all their goods.
NIV
and the earth opened its mouth and swallowed them and their households, and all those associated with Korah, together with their possessions.
Numbers 16:27 “stood in the door of their tents” and Numbers 26:11 “Notwithstanding the children of Korah died not” show that the term “houses” not “households” is correct.
