Proverbs 30:15-16

The leech has two daughters:
    Give and Give.
Three things are never satisfied;
    four never say, “Enough”:
¹⁶ Sheol, the barren womb,
    the land never satisfied with water,
    and the fire that never says, “Enough.”

Proverbs 30:15-16 ESV

In this passage, Agur uses the image of a leech to describe a negative characteristic or trait of a self-absorbed person; the person who only says, “Give me.” For this person, enough is never enough. “Give me,” he says. For this person, the focus is always self. “Give me,” he says. For this person the needs or supply of another is of no consequence. “Give me,” he says.

To make his point more clear, Agur uses a few more images of things that are never satisfied: the grave, the barren womb; the land in drought; and a fire.

The point: Don’t be like the leech. Don’t always say, “Give me.”
