'Dregs' in the Bible

"Awake, Awake! Stand up, Jerusalem, you who have drunk from the LORD's hand from the cup that is his anger. You have drunk to the dregs the cup that makes you stagger, and have drained it.

This is what your Lord, the LORD, says, your God, who defends his people's cause: "See, I have taken from your hand the cup that made you stagger. And you will never again drink to the dregs the cup that is my anger.
