Proverbs 30:15-17 ESV
The leech has two daughters:
Give and Give.
Three things are never satisfied;
four never say, “Enough”:
Sheol, the barren womb,
the land never satisfied with water,
and the fire that never says, “Enough.”
The eye that mocks a father
and scorns to obey a mother
will be picked out by the ravens of the valley
and eaten by the vultures.
