'Dregs' in the Bible

For a cup [of His wrath] is in the hand of the Lord, and the wine foams;It is well mixed and fully spiced, and He pours out from it;And all the wicked of the earth must drain it and drink down to its dregs.

Wake yourself up! Wake yourself up! Stand up, O Jerusalem,You who have drunk at the hand of the Lord the cup of His wrath,You who have drunk the cup of staggering and intoxication to the dregs [leaving only sediment].

But more than that, I count everything as loss compared to the priceless privilege and supreme advantage of knowing Christ Jesus my Lord [and of growing more deeply and thoroughly acquainted with Him—a joy unequaled]. For His sake I have lost everything, and I consider it all garbage, so that I may gain Christ,
