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.

And Moses spake unto the children of Israel, and every one of their princes gave him a rod apiece, for each prince one, according to their fathers' houses, even twelve rods: and the rod of Aaron was among their rods.

We will not return unto our houses, until the children of Israel have inherited every man his inheritance.
