Context19:21 “‘So this will be a perpetual ordinance for them: The one who sprinkles 3 the water of purification must wash his clothes, and the one who touches the water of purification will be unclean until evening. 4 19:22 And whatever the unclean person touches will be unclean, and the person who touches it will be unclean until evening.’”
1 sn Here the text makes clear that he had at least one assistant.
2 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.
