'Dregs' in the Bible

For in the hand of the LORD there is a cup, and the wine is red; it is full of mixture; and he poureth out of the same: but the dregs thereof, all the wicked of the earth shall wring them out, and drink them.

Awake, awake, stand up, O Jerusalem, which hast drunk at the hand of the LORD the cup of his fury; thou hast drunken the dregs of the cup of trembling, and wrung them out.

Thus saith thy Lord the LORD, and thy God that pleadeth the cause of his people, Behold, I have taken out of thine hand the cup of trembling, even the dregs of the cup of my fury; thou shalt no more drink it again:

Moab has been left quiet since his youth,settled like wine on its dregs.He hasn’t been poured from one container to anotheror gone into exile.So his taste has remained the same,and his aroma hasn’t changed.

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."
