Proverbs 30:15-16

15 The leech has two daughters:
Give and Give.
Or  Give, give,” they cry

eThree things are never satisfied;
ffour never say, “Enough”:
16 gSheol, hthe barren womb,
the land never satisfied with water,
and the fire that never says, “Enough.”

Ecclesiastes 5:10

10He who loves money will not be satisfied with money, nor he who loves wealth with his income; this also is vanity.
