'Dregs' in the Bible

For a cup is in the hand of the Lord, and the wine foams;It is well mixed, and He pours out of this;Surely all the wicked of the earth must drain and drink down its dregs.

Rouse yourself! Rouse yourself! Arise, O Jerusalem,You who have drunk from the Lord’s hand the cup of His anger;The chalice of reeling you have drained to the dregs.
