Numbers 19:19

[19:7]  ³ tn This is the imperfect of permission.

[19:19]  ⁵ tn The construction uses a simple Piel of חָטָא (khata’, “to purify”) with a pronominal suffix – “he shall purify him.” Some commentators take this to mean that after he sprinkles the unclean then he must purify himself. But that would not be the most natural way to read this form.
