'Dregs' in the Bible

For in the hand of Yahweh there is a cup, full of foaming wine mixed with spices. He pours it out. Indeed the wicked of the earth drink and drink it to its very dregs.

It will happen at that time, that I will search Jerusalem with lamps, and I will punish the men who are settled on their dregs, who say in their heart, "Yahweh will not do good, neither will he do evil."
