'Cup' in the Bible

And whoever gives to one of these little ones [these who are humble in rank or influence] even a cup of cold water to drink because he is my disciple, truly I say to you, he will not lose his reward.”

But Jesus replied, “You do not realize what you are asking. Are you able to drink the cup [of suffering] that I am about to drink?” They answered, “We are able.”

He said to them, “You will drink My cup [of suffering]; but to sit on My right and on My left this is not Mine to give, but it is for those for whom it has been prepared by My Father.”

“Woe to you, [self-righteous] scribes and Pharisees, hypocrites! For you clean the outside of the cup and of the plate, but inside they are full of extortion and robbery and self-indulgence (unrestrained greed).

You [spiritually] blind Pharisee, first clean the inside of the cup and of the plate [examine and change your inner self to conform to God’s precepts], so that the outside [your public life and deeds] may be clean also.

And when He had taken a cup and given thanks, He gave it to them, saying, “Drink from it, all of you;

And after going a little farther, He fell face down and prayed, saying, “My Father, if it is possible [that is, consistent with Your will], let this cup pass from Me; yet not as I will, but as You will.”
