15 "A bloodsucking worm has two daughters. They cry out, 'Give! Give!' "Three things are never satisfied. Four things never say, 'Enough!'
16 The first is the grave. The second is a woman who can't have a baby. The third is land. It never gets enough water. And the fourth is fire. It never says, 'Enough!'
17 "Some make fun of their fathers. Others laugh about obeying their mothers. The ravens of the valley will peck their eyes out. Then the vultures will eat them.
18 "Three things are too amazing for me. There are four things I don't understand.
19 The first is the way of an eagle in the sky. The second is the way of a snake on a rock. The third is the way of a ship on the ocean. And the fourth is the way of a man with a young woman.
20 "This is the way of a woman who commits adultery. She eats. She wipes her mouth. Then she says, 'I haven't done anything wrong.'
21 "Under three things the earth shakes. Under four things it can't stand up.
