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.”
By wisdom a house is built, and by understanding it is established. By knowledge the rooms are filled with all precious and pleasant riches.
(Proverbs 24:3-4 NRSV)
