Side-ring EXTRA · Language of the renovations
Rashi on Vayikra 14:43.
English: “Hiktzos” is in the passive/stative form of being done, and so is “hittoach”; but “chiletz the stones” turns the language toward the person who removed them, and it is a heavy (intensive) verbal pattern, like kipper, dibber.
Precision of the verbs
Rashi distinguishes the agent-focused removal of stones from the process-focused scraping and plastering — all of which must be complete before a returning nega is judged under this verse.
