remembrances - “proverbial maxims,” so called because well remembered.
like unto ashes - or, “parables of ashes”; the image of lightness and nothingness (Isa 44:20).
bodies - rather, “entrenchments”; those of clay, as opposed to those of stone, are easy to be destroyed; so the proverbs, behind which they entrench themselves, will not shelter them when God shall appear to reprove them for their injustice to Job.
