'Drink the Cup' in the Bible

Jesus replied, "You do not know what you are asking. Can you drink the cup I am going to drink?" They said to him, "We can."

Jesus said, "You do not know what you are asking. Can you drink the cup I have to drink, or undergo the baptism I have to undergo?"

They said to him, "We can." Jesus said, "You shall drink the cup I have to drink and undergo the baptism I have to undergo;

whereupon Jesus said to Peter, "Sheathe your sword. Am I not to drink the cup which the Father has handed me?"

You cannot drink the cup of the Lord and also the cup of daemons; you cannot partake of the table of the Lord and also of the table of daemons.
