Proverbs 30:18

3

"There are three things which are too wonderful for me,

Yea, four which I know not:

The way of an eagle in the air;

The way of a serpent on a rock;

The way of a ship in the midst of the sea;

And the way of a man with a maiden.

So is the way of an adulterous woman;

She eateth, and wipeth her mouth,

And saith, I have done no wickedness."

In the preceding tetrad, the concurrence of the four things was in their insatiable nature; here the quadruple likeness is that, "They leave no trace behind them."[18] Fritsch wrote that the reference in the fourth instance here was, "To sexual union, or possibly defloration";[19] but his support of that opinion was weak.

Of course, the adulteress that eats and wipes her mouth is a metaphor describing her casual immorality and has nothing to do with eating.
