Proverbs 30:14-16

Amplified Bible

¹⁴ 
There is a generation (class of people) whose teeth are like swords
And whose jaw teeth are like knives,
To devour the afflicted from the earth
And the needy from among men.

¹⁵ 
The leech has two daughters,
“Give, give!”
There are three things that are never satisfied,
Four that do not say, “It is enough”:
^16 
[a]Sheol, and the barren womb,
Earth that is never satisfied with water,
And fire that never says, “It is enough.”
