2 Kings 5:25

5:25 When he came and stood before his master, Elisha asked him, “Where have you been, Gehazi?” He answered, “Your servant hasn’t been anywhere.”

Proverbs 30:20

30:20 This is the way ¹  of an adulterous ²  woman:

she eats and wipes her mouth ³ 

and says, “I have not done wrong.” ⁴ 

[30:20]  ¹ 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.

[30:20]  ² 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.

[30:20]  ³ 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).

[30:20]  ⁴ 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.
