30:12 There is a generation who are pure in their own eyes
and yet are not washed 1 from their filthiness. 2
30:20 This is the way 3 of an adulterous 4 woman:
she eats and wipes her mouth 5
and says, “I have not done wrong.” 6
1 tn The verb רָחַץ (rakhats) means “to wash; to wash off; to wash away; to bathe.” It is used of physical washing, ceremonial washings, and hence figuratively of removing sin and guilt through confession (e.g., Isa 1:16). Here the form is the Pual perfect (unless it is a rare old Qal passive, since there is no Piel and no apparent change of meaning from the Qal).
sn The point of the verse is that there are people who observe outer ritual and think they are pure (טָהוֹר [tahor] is the Levitical standard for entrance into the sanctuary), but who pay no attention to inner cleansing (e.g., Matt 23:27).
2 sn Filthiness often refers to physical uncleanness, but here it refers to moral defilement. Zech 3:3-4 uses it metaphorically as well for the sin of the nation (e.g., Isa 36:12).
3 sn Equally amazing is the insensitivity of the adulterous woman to the sin. The use of the word “way” clearly connects this and the preceding material. Its presence here also supports the interpretation of the final clause in v. 19 as referring to sexual intimacy. While that is a wonder of God’s creation, so is the way that human nature has distorted it and ruined it.
4 sn The word clearly indicates that the woman is married and unchaste; but the text describes her as amoral as much as immoral – she sees nothing wrong with what she does.
5 sn The acts of “eating” and “wiping her mouth” are euphemistic; they employ an implied comparison between the physical act of eating and wiping one’s mouth afterward on the one hand with sexual activity on the other hand (e.g., Prov 9:17).
6 sn This is the amazing part of the observation. It is one thing to sin, for everyone sins, but to dismiss the act of adultery so easily, as if it were no more significant than a meal, is incredibly brazen.
