'Cup' in the Bible

For whoever will give you a cup of water to drink in my name, because you are Christ's, most certainly I tell you, he will in no way lose his reward.

But Jesus said to them, "You don't know what you are asking. Are you able to drink the cup that I drink, and to be baptized with the baptism that I am baptized with?"

They said to him, "We are able." Jesus said to them, "You shall indeed drink the cup that I drink, and you shall be baptized with the baptism that I am baptized with;

He took the cup, and when he had given thanks, he gave to them. They all drank of it.

He said, "Abba, Father, all things are possible to you. Please remove this cup from me. However, not what I desire, but what you desire."
