'Drink the Cup' in the Bible

And Jesus responding said, You know not what you are asking. Are you able to drink the cup which I am about to drink? They say to Him, We are able.

And Jesus said to them, You know not what you are asking. Are you able to drink the cup which I drink? and to be baptized with the baptism with which I am baptized?

And they said to Him, We are able. And Jesus said to them, You shall indeed drink the cup which I drink, and be baptized with the baptism with which I am baptized:

You are not able to drink the cup of the Lord, and the cup of demons: you are not able to partake of the table of the Lord, and the table of demons.

For as often as you may eat this bread, and drink the cup, you do proclaim the death of the Lord, until he may come.

So whosoever may eat the bread or drink the cup of the Lord unworthily, shall be guilty of the body and the blood of the Lord.
