Proverbs 30:20

18 There be three things which are too wonderful for me, yea, four which I know not:

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.

Such is the way of an adulterous woman; she eateth, and wipeth her mouth, and saith, I have done no wickedness.

21 For three things the earth is disquieted, and for four which it cannot bear:

22 For a servant when he reigneth; and a fool when he is filled with meat;

This was said to Israel at a particular time, so it is wise to read it together with the surrounding text. Do read the surrounding verses too, because the context often says more than a single verse.
