tn The verb is the Hitpael of חָטָא (khata’), a verb that normally means “to sin.” But the Piel idea in many places is “to cleanse; to purify.” This may be explained as a privative use (“to un-sin” someone, meaning cleanse) or denominative (“make a sin offering for someone”). It is surely connected to the purification offering, and so a sense of purify is what is wanted here.
