Proverbs 30:18

14 there is a generation whose teeth are swords and whose jaws are knives, devouring the oppressed from the earth and the needy from among men.

15 The leech has two daughters: Give and Give. There are three things that are never satisfied, four that never say, ‘Enough!’:

16 Sheol, the barren womb, land never satisfied with water, and fire that never says, ‘Enough!’

17 As for the eye that mocks a father and scorns obedience to a mother, may the ravens of the valley pluck it out and young vultures devour it.

18 There are three things too wonderful for me, four that I cannot understand:

19 the way of an eagle in the sky, the way of a snake on a rock, the way of a ship at sea, and the way of a man with a maiden.

20 This is the way of an adulteress: She eats and wipes her mouth and says, ‘I have done nothing wrong.’

21 Under three things the earth trembles, under four it cannot bear up:
