'Enough' in the Bible

The righteous has enough to satisfy his appetite,But the stomach of the wicked is in need.

And there will be goats’ milk enough for your food,For the food of your household,And sustenance for your maidens.

The leech has two daughters,“Give,” “Give.”There are three things that will not be satisfied,Four that will not say, “Enough”:

Sheol, and the barren womb,Earth that is never satisfied with water,And fire that never says, “Enough.”
