Their inward thought [is, that] their houses [shall continue] for ever,.... This is the thought of their hearts, what they secretly imagine, and conclude within themselves; either that their families, which may be meant by their houses, see 2Sa 3:1; shall continue in succeeding ages, to the end of the world, to inherit their possessions, and perpetuate their name; though often so it is, that great families become extinct, and the seed of the wicked is cut off: or that their magnificent buildings, which they have erected to dwell in, and for their honour and glory, shall abide for ever; though in a little time, so it is by one means or another, like the buildings of the temple, not one stone is left upon another.
Or the words may be rendered, "in the midst of them" (their heirs to whom they leave their wealth) "their houses shall remain for ever", so Aben Ezra; that is, so they fancy they will; but this is not always true, for fine houses and large estates belonging to them often pass into other hands and families.
