Proverbs 30:18-20

New Revised Standard Version, Anglicised Catholic Edition

¹⁸ Three things are too wonderful for me;
    four I do not understand:
¹⁹ the way of an eagle in the sky,
    the way of a snake on a rock,
the way of a ship on the high seas,
    and the way of a man with a girl.

²⁰ This is the way of an adulteress:
    she eats, and wipes her mouth,
    and says, ‘I have done no wrong.’
