Pro 30:15 The horseleach hath two daughters, crying, Give, give. There are three things that are never satisfied, yea, four things say not, It is enough:
Pro 30:16 The grave; and the barren womb; the earth that is not filled with water; and the fire that saith not, It is enough.
Pro 30:17 The eye that mocketh at his father, and despiseth to obey his mother, the ravens of the valley shall pick it out, and the young eagles shall eat it.
Pro 30:18 There be three things which are too wonderful for me, yea, four which I know not:
Pro 30:19 The way of an eagle in the air; the way of a serpent upon a rock; the way of a ship in the midst of the sea; and the way of a man with a maid.
Pro 30:20 Such is the way of an adulterous woman; she eateth, and wipeth her mouth, and saith, I have done no wickedness.
The image from that last verse is incredible. If we go back to the various ways one might see the adulterous woman in Proverbs, then this is even more telling.
